Windows Update is a Microsoft service for the Windows 9x and Windows NT families of operating system, which automates downloading and installing Microsoft Windowssoftware updates over the Internet. The service delivers software updates for Windows, as well as the various Microsoft antivirus products, including Windows Defender and Microsoft Security Essentials. Since its inception, Microsoft has introduced two extensions of the service: Microsoft Update and Windows Update for Business. The former expands the core service to include other Microsoft products, such as Microsoft Office and Microsoft Expression Studio. The latter is available to business editions of Windows 10 and permits postponing updates or receiving updates only after they have undergone rigorous testing.
As the service has evolved over the years, so have its client software. For a decade, the primary client component of the service was the Windows Update web app that could only be run inside Internet Explorer. Starting with Windows Vista, the primary client component became Windows Update Agent, an integral component of the operating system.
The service provides several kinds of updates. Security updates or critical updates mitigate vulnerabilities against security exploits against Microsoft Windows. Cumulative updates are updates that bundle previously released updates. Cumulative updates were introduced with Windows 10 and have been backported to Windows 7 and Windows 8.1.
Microsoft routinely releases updates on the second Tuesday of each month (known as the Patch Tuesday), but can provide them whenever a new update is urgently required to prevent a newly discovered or prevalent exploit. System administrators can configure Windows Update to install critical updates for Microsoft Windows automatically, so long as the computer has an Internet connection.

Windows Update web app[edit]
The Windows Update web app, version 4, in Windows ME
Windows Update was introduced as a web app with the launch of Windows 98 and offered additional desktop themes, games, device driver updates, and optional components such as NetMeeting.[1] Windows 95 and Windows NT 4 were retroactively given the ability to access the Windows Update website, and download updates designed for those operating systems, starting with the release of versions of Internet Explorer 4. The initial focus of Windows Update was free add-ons and new technologies for Windows. Security fixes for Outlook Express, Internet Explorer and other programs appeared later, as did access to beta versions of upcoming Microsoft software, e.g., Internet Explorer 5. Fixes to Windows 98 to resolve the Year 2000 problem were distributed using Windows Update in December 1998. Microsoft attributed the sales success of Windows 98 in part to Windows Update.[2]
The Windows Update web app requires either Internet Explorer or a third-party web browser that supports the ActiveX technology. The first version of the web app, version 3, does not send any personally-identifiable information to Microsoft. Instead, the app downloads a full list of every available update and chooses which one to download and install. But the list grew so large that the performance impact of processing became a concern. Arie Slob, writing for the Windows-help.net newsletter in March 2003, noted that the size of the update list had exceeded 400 KB, which caused delays of more than a minute for dial-up users.[3] Windows Update v4, released in 2001 in conjunction with Windows XP, changed this. This version of the app makes an inventory of the system's hardware and Microsoft software and sends them to the service, thus offloading the processing burden to Microsoft servers.[3]
Critical Update Notification Utility[edit]

Vmware Vsphere Replication 8.1 1 Release Notes
Critical Update Notification Utility (initially Critical Update Notification Tool) is a background process that checks the Windows Update web site on a regular schedule for new updates that have been marked as 'Critical'. It was released shortly after Windows 98.
By default, this check occurs every five minutes, plus when Internet Explorer starts; however, the user could configure the next check to occur only at certain times of the day or on certain days of the week. The tool queries the Microsoft server for a file called '
cucif.cab
', which contained a list of all the critical updates released for the operating system. The tool then compares this list with the list of installed updates on its machine and displays an update availability notification. Once the check is executed, any custom schedule defined by the user is reverted to the default. Microsoft stated that this ensures that users received notification of critical updates in a timely manner.[4]An analysis done by security researcher H. D. Moore in early 1999 was critical of this approach, describing it as 'horribly inefficient' and susceptible to attacks. In a posting to BugTraq, he explained that, 'every single Windows 98 computer that wishes to get an update has to rely on a single host for the security. If that one server got compromised one day, or an attacker cracks the [Microsoft] DNS server again, there could be millions of users installing trojans every hour. The scope of this attack is big enough to attract crackers who actually know what they are doing..'[5]
Microsoft continued to promote the tool through 1999 and the first half of 2000. Initial releases of Windows 2000 shipped with the tool. The tool did not support Windows 95 and Windows NT 4.0.
Automatic Updates[edit]
Automatic Updates 'Restart Required' dialog box in Windows XP SP1
Automatic Updates is the successor of the Critical Update Notification Utility. It was released in 2000, along with Windows ME. It supports Windows 2000 SP3 as well.
Unlike its predecessor, Automatic Updates can download and install updates. Instead of the five-minute schedule used by its predecessor, Automatic Updates checks the Windows Update servers once a day. After Windows ME is installed, a notification balloon prompts the user to configure the Automatic Updates client. The user can choose from three notification schemes: Being notified before downloading the update, being notified before installing the update, or both.
Windows XP and Windows 2000 SP3 include Background Intelligent Transfer Service, a Windows service for transferring files in the background without user interaction. As a system component, it is capable of monitoring the user's Internet usage, and throttling its own bandwidth usage in order to prioritize user-initiated activities. The Automatic Updates client for these operating systems was updated to use this system service.
Automatic Updates in Windows XP gained notoriety for repeatedly interrupting the user while working on their computer. Every time an update requiring a reboot was installed, Automatic Updates would prompt the user with a dialog box. That allowed the user to restart immediately, or dismiss the dialog box, which would reappear in ten minutes, a behavior Jeff Atwood described as 'perhaps the naggiest dialog box ever.'[6]
In 2013, it was observed that shortly after the startup process, Automatic Updates (
wuauclt.exe
) and Service Host (svchost.exe)
in Windows XP would claim 100% of a computer's CPU capacity for extended periods of time (between ten minutes to two hours), making affected computers unusable. According to Woody Leonhart of InfoWorld, early reports of this issue could be seen in Microsoft TechNetforums in late May 2013, although Microsoft first received large number of complaints about this issue in September 2013. The cause was an exponential algorithm in the evaluation of superseded updates which had grown large over the decade following the release of Windows XP. Microsoft's attempts to fix the issue in October, November and December proved futile, causing the issue to be escalated to the top priority.[7][8]Windows Update Agent[edit]
Revised restart dialog box in Windows Vista
Starting with Windows Vista and Windows Server 2008, Windows Update Agent replaces both the Windows Update web app and the Automatic Updates client.[9][10] It is in charge of downloading and installing software update from Windows Update, as well as the on-premises servers of Windows Server Updates Services or System Center Configuration Manager.[11][12]
Windows Update Agent can be managed through a Control Panel applet, as well as Group Policy, Microsoft Intune and Windows PowerShell. It can also be set to automatically download and install both important and recommended updates. In prior versions of Windows, such updates were only available through the Windows Update web site. Additionally, Windows Update in Windows Vista supports downloading Windows Ultimate Extras, optional software for Windows Vista Ultimate Edition.
Unlike Automatic Updates in Windows XP, Windows Update Agent in Windows Vista and Windows 7 allows the user to postpone the mandatory restart (required for the update process to complete) for up to four hours. The revised dialog box that prompts for the restart appears under other windows, instead of on top of them. However, standard user accounts only have 15 minutes to respond to this dialog box. This was changed with Windows 8: Users have 3 days (72 hours) before the computer reboots automatically after installing automatic updates that require a reboot. Windows 8 also consolidates the restart requests for non-critical updates into just one per month. Additionally, the login screen notifies them of the restart requirements.[13]
Windows Update Agent makes use of the Transactional NTFS feature introduced with Windows Vista to apply updates to Windows system files. This feature helps Windows recover cleanly in the event of an unexpected failure, as file changes are committed atomically.[14]
Windows 10 contains major changes to Windows Update Agent operations; it no longer allows the manual, selective installation of updates. All updates, regardless of type (this includes hardware drivers), are downloaded and installed automatically, and users are only given the option to choose whether their system would reboot automatically to install updates when the system is inactive, or be notified to schedule a reboot.[15][16] Microsoft offers a diagnostic tool that can be used to hide troublesome device drivers and prevent them from being reinstalled, but only after they had been already installed, then uninstalled without rebooting the system.[17][18]
Vsphere Replication Appliance Failed To Check For Updates
Windows Update Agent on Windows 10 supports peer to peer distribution of updates; by default, systems' bandwidth is used to distribute previously downloaded updates to other users, in combination with Microsoft servers. Users may optionally change Windows Update to only perform peer to peer updates within their local area network.[19]
Windows 10 also introduced cumulative updates. For example, if Microsoft released updates KB00001 in July, KB00002 in August, and KB00003 in September, Microsoft would release cumulative update KB00004 which packs KB00001, KB00002, and KB00003 together. Installing KB00004 will also install KB00001, KB00002 and KB00003, mitigating the need for multiple restarts and reducing the number of downloads needed. However, a disadvantage of cumulative updates is that downloading and installing updates that fix individual problems is no longer possible.
Windows Update for Business[edit]
Windows Update for Business is a term for a set of features in the Pro, Enterprise and Education editions of Windows 10, including:[20][21][22]
- The ability to change the Windows 10 release branch from the default 'Semi-Annual Channel (Targeted)' (formerly 'Current Branch' or 'CB') to 'Semi-Annual Channel' (formerly 'Current Branch for Business' or 'CBB'), or vice versa. The former offers feature updates as soon as they are released. The latter offers feature updates with a four-month delay, so that they may receive further testing.
- The ability to delay quality updates for up to 30 days.
- The ability to delay feature updates for up to 365 days.
These features were added in Windows 10 version 1511.[23] They are intended for large organizations with lots of computers, so that they can logically group their computers for gradual deployment. Microsoft recommends a small set of pilot computers to receive the updates almost immediately, while the set of most critical computers to receive them after every other group has done so, and has experienced their effects.[24]
Other Microsoft update management solutions, such as Windows Server Update Services or System Center Configuration Manager, do not override Windows Update for Business. Rather, they force Windows 10 into the 'dual scan mode'. This can cause confusion for administrators who do not comprehend the full ramifications of the dual scan mode.[25]

Complementary software and services[edit]
As organizations continued to use more computers, the per-machine Windows Update clients started to become unwieldy and insufficient. In response to the need of organizations for deploying updates to many machines, Microsoft introduced what was ultimately called Windows Server Update Services (WSUS). WSUS downloads updates for Microsoft product to a server computer on which it is running and redistributes them to the computers within the organization over a local area network (LAN). One of the benefits of this method is a reduction in the consumption of Internet bandwidth, equal to (N-1)×S, where N is the number of computers in the organization and S is the size made by the updates. Additionally, WSUS permits administrators to test updates on a small group of test computers before deploying them to all systems, in order to ensure that business continuity is not disrupted because of the changes of the updates. For very large organizations, multiple WSUS servers can be chained together hierarchically. Only one server in this hierarchy downloads from the Internet. WSUS is a component of the Windows Server family of operating systems.
Update packages distributed via the Windows Update service can be individually downloaded from Microsoft Update Catalog. These updates can be delivered to computers without any network connections (e.g. using a USB flash drive) or used deploy Microsoft products in pre-updated state. In case of the former, Windows Update Agent (
wusa.exe
) can install these files. In case of the latter, Microsoft deployment utilities such as DISM, WADK and MDT can consume these packages.Microsoft offers System Center Configuration Manager for very complex deployment and servicing scenarios. The product integrates with all of the aforesaid tools (WSUS, DISM, WADK, MDT) to automate the process.
Service[edit]
At the beginning of 2005, Windows Update was being accessed by about 150 million people,[26] with about 112 million of those using Automatic Updates.[27]
As of 2008, Windows Update had about 500 million clients, processed about 350 million unique scans per day, and maintained an average of 1.5 million simultaneous connections to client machines. On Patch Tuesday, the day Microsoft typically releases new software updates, outbound traffic could exceed 500 gigabits per second.[28] Approximately 90% of all clients used automatic updates to initiate software updates, with the remaining 10% using the Windows Update web site. The web site is built using ASP.NET, and processes an average of 90,000 page requests per second.
Traditionally, the service provided each patch in its own proprietary archive file. Occasionally, Microsoft released service packs which bundled all updates released over the course of years for a certain product. Starting with Windows 10, however, all patches are delivered in cumulative packages.[29] On 15 August 2016, Microsoft announced that effective October 2016, all future patches to Windows 7 and 8.1 would become cumulative as with Windows 10. The ability to download and install individual updates would be removed as existing updates are transitioned to this model.[30] This has resulted in increasing download sizes of each monthly update. An analysis done by Computerworld determined that the download size for Windows 7 x64 has increased from 119.4MB in October 2016 to 203MB in October 2017.[31] Initially, Microsoft was very vague about specific changes within each cumulative update package.[29] However, since early 2016, Microsoft has begun releasing more detailed information on the specific changes.[32]
Microsoft Update[edit]

At the February 2005 RSA Conference, Microsoft announced the first beta of Microsoft Update, an optional replacement for Windows Update that provides security patches, service packs and other updates for both Windows and other Microsoft software.[33] The initial release in June 2005 provided support for Microsoft Office 2003, Exchange 2003, and SQL Server 2000, running on Windows 2000, XP, and Server 2003. Over time, the list has expanded to include other Microsoft products, such as Windows Live, Windows Defender, Visual Studio, runtimes and redistributables, Zune Software, Virtual PC and Virtual Server, CAPICOM, Microsoft Lync, Microsoft Expression Studio, and other server products. It also offers Silverlight and Windows Media Player as optional downloads if applicable to the operating system.
Office Update[edit]
Office Update is a free online service that allows users to detect and install updates for certain Microsoft Office products.

On 1 August 2009 Microsoft decommissioned the Office Update service, merging it with Microsoft Update.[34] Microsoft Update does not support Office 2000.
With the introduction of the Office 365 licensing program, however, Microsoft once again activated a separate Office update service to service Office 365 customers. Owners of perpetual Microsoft Office licenses continue to receive updates through Microsoft Update.[35][36]
Alternative tools[edit]
A number of tools have been created by independent software vendors which provide the ability for Windows Updates to be automatically downloaded for, or added to, an online or offline system. One common use for offline updates is to ensure a system is fully patched against security vulnerabilities before being connected to the Internet or another network. A second use is that downloads can be very large, but may be dependent on a slow or unreliable network connection, or the same updates may be needed for more than one machine. AutoPatcher, WSUS Offline Update, PortableUpdate, and Windows Updates Downloader are examples such tools.[37]
Controversy[edit]
The June 2019 Windows Update disabled bluetooth for any device using common encryption codes[38] (causing a blue screen of death if one is used). This was done without the usual warning 4 or 2 months ahead of time[39], causing some companies to fold rather than deal with the massive amounts of calls from 100% of their bluetooth enabled devices being broken by the update. In addition to mice headphones and other pepherials, security fobs were affected (presumably causing the affected businesses to shut down for a few days while they replaced all their fobs).

Hi John,
Vsphere Replication 8.1 Upgrade
I would suggest you to follow these methods and check if it helps.
If you receive Windows Update error 80070103 while installing updates, you might be trying to install a driver that is already installed on your computer or a driver that has a lower compatibility rating than one you already have installed.
I would suggest you to install the latest driver from manufactuer's website.
Intel Graphic card
Now, try to run the Windows updates again. If it still shows up, then, hide the update so it is not offered again, click the plus sign (+) under the title of the update, and then select the Don't show this update again check box.
For to install Windows 8.1 from Store, I would suggest you to follow these methods.
Method 1:
I would suggest you to reset Windows Store Cache and check if it helps.
Method 1:
I would suggest you to reset Windows Store Cache and check if it helps.
a) Press 'Windows Key +R' on the keyboard to open Run Window.
b) In the Run Window type 'wsreset.exe' and then click Ok.
Method 2:
I would also suggest you to disable anti-virus program on the PC temporarily and then try to install Windows 8.1
Important: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable or uninstall your antivirus software. If you have to temporarily disable or uninstall it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled or uninstalled, your computer is vulnerable to attacks.
Let us know if it helps. If the issue perists, please reply, we will be glad to assist you further.
Windows Update is sometimes underestimated as a cornerstone of your system’s integrity and security. Microsoft also delivers featured OS updates from Windows Update, including the Windows 10 October 2018 Update that was just re-released after a fitful start, and so you’ll need to make sure that it’s up and running. The update process has been greatly streamlined for Windows 10, but that doesn’t mean it’s always problem-free, especially when it comes to compatibility and patches.
Here, we’ll show you how to get Windows Update working again when it fails, and what to do if it looks like an update is causing problems.
Manage when automatic updates reboot your machine
You can’t permanently turn off automatic updates in Windows 10, but you can manage when your machine reboots after installing an update. That way, you can at least make sure your machine doesn’t restart during your workday or at an inconvenient time. Here’s how:
Step 1: Go to or search for Settings. Then select Update & Security options.
Step 2: Select the Windows Update tab at the top of the list on the left-hand side. Then, click Change active hours at the bottom of the window.
Step 3: This will bring up a window called Active hours, which will let you set a start and end time for when restarts will occur. Keep in mind that this doesn’t change when updates are installed, but only when your machine will automatically restart — and then, only when you’re not actively using it. Select your preferred times, and click Save.
Step 4: If an update has already been scheduled, then you can select Restart options from the main Windows Update settings page to select a custom restart time. Just toggle the setting on, and then select your preferred time and day.
Step 5: Finally, you can defer system upgrades for a period of time if you so choose, or pause them temporarily. Keep in mind that there are separate settings for major updates, like the October 2018 Update, and for quality updates like security updates.
To defer upgrades, select Advanced Options on the main Windows Update page. Use the drop-down lists to decide how many days you want to defer them for.
You can also use this menu to make other adjustments to the way updates are applied, including whether they’re automatic or manually triggered. You even have the option to pause them entirely.
Run the Windows Update Troubleshooter
Microsoft knows that sometimes things like the Windows 10 October 2018 Update can bring along a few unwanted issues, which is why the company created the Windows Update Troubleshooter. This tool will run through your basic operating system parameters and look for any obvious problems that may be keeping Windows Update from functioning correctly. If it can, the troubleshooter will also fix them automatically, or at least let you know what the issue is.
Try this analysis early on if you’re experiencing update issues. Head over to Microsoft’s support page and click Download troubleshooter for Windows 10— the tool should take care of the rest. It might ask you for administrator privileges to perform a deeper check, but beyond giving it permission to do so, you don’t need to do anything else.
It won’t solve every problem, but it’s a great place to start and will usually provide useful information even if it can’t offer a fix.
Check your installation error code
If your general update or featured update to the Windows 10 April or October 2018 Update fails or creates problems, it will often give you an installation error code. The codes don’t tell you much by themselves, but they do include a lot of useful info if you hop online and consult Microsoft’s guide on the matter. Below, we’ve included a table highlighting some of the more common errors.
0x80073712 | A file needed by Windows Update is likely damaged or missing. |
0x800F0923 | This might indicate that a driver or other software on your PC isn’t compatible with the upgrade to Windows 10. For info about how to fix this problem, contact Microsoft support. |
0x80200056 | This could mean that the upgrade process was interrupted because you accidentally restarted your PC or signed out of your PC. Try upgrading again and make sure your PC is plugged in and stays turned on. |
0x800F0922 | This error might mean that your PC couldn’t connect to the Windows Update servers. If you’re using a VPN connection to connect to a work network, disconnect from the network and turn off the VPN software (if applicable) and try upgrading again. The error could also mean there isn’t enough free space in the System Reserved partition. You might be able to fix this problem by using third-party software to increase the size of the System Reserved partition. |
0xC1900208 – 0x4000C | This could indicate that an incompatible app installed on your PC is blocking the upgrade process from completing. Check to make sure that any incompatible apps are uninstalled and then try upgrading again. |
0xC1900202 – 0x20008 | This may signify that your PC doesn’t meet the minimum requirements to download or install the upgrade to Windows 10. |
0x80070070 – 0x50012 | This likely indicates that your PC doesn’t have enough space available to install the upgrade. Free some space on the drive and try again. |
Note that this guide is designed specifically for Windows 10 and recent versions like the October 2018 Update. Error codes may not mean the same thing in other versions of Windows.
If all else fails, these quick fixes might do it
Have all the automatic checks and codes failed you? It’s time to go back to the tried-and-true methods, the tricks that have been solving update errors since the update was first invented. Here are a few options that may work for you.
Reboot your computer
This is a surprisingly effective method that will solve a host of computer issues — and it often works for Windows Update. When you encounter an error message, reboot your machine and try to run the updates again. If you haven’t run Windows Update for some time, then you might have to repeat this process several times before all updates have been installed.
Do you have enough disk space?
One scenario in which updates may fail is when your system drive is running out of space. Double-check that you have at least 10GB of free space. If you don’t, perform a disk cleanup to remove files. To do so, type Disk Cleanup into Cortana’s search box, click Disk Cleanup to start the utility, and, if requested, select your system drive (usually C:). Afterward, specify the type of files that you want to get rid of and select OK. Try to stay away from important system files.
Alternatively, third-party software like CCleaner can be great for freeing up extra space on your system. For more information on this topic, check out our more complete guide on managing Windows 10’s storage space.
Is malware causing the issue?
Malware can change critical system files and break Windows services, meaning it’s a good idea to run a malware scanner to make sure your system isn’t compromised. If you don’t have any sort of antivirus software, check out some of our personal favorites for Windows-based machines. After all, sorting through heaps and heaps of software is never fun — and neither is paying.
Contact Microsoft support
If you’ve done everything you can, it’s time to contact Microsoft support and see if they can pinpoint the issue. Head over to the company’s contact page, where you can start a chat, request a call back, or schedule a call. There’s also an option to ask the community, which may be a bit more time-consuming but can be useful if others have already encountered and fixed the update issue.

Windows Anytime Upgrade is a discontinued component of Windows Vista and Windows 7 that enabled users to upgrade their editions of Windows (e.g., from Home Basic to Ultimate).[1] Pricing for upgrades purchased through Anytime Upgrade was also reduced when compared with traditional retail packaging.[2][3] In Windows 8 and Windows 8.1, the feature was re-branded as Add features to Windows and was used to purchase an upgrade license to the Pro edition of the operating system or to add Windows Media Center to an existing Pro edition installation. However, support for this feature in Windows 8 and Windows 8.1 was dropped on October 31, 2015.[4]

History[edit]
A preliminary version of Anytime Upgrade in Windows Vista build 4093
Windows Anytime Upgrade was in development prior to the development reset of Windows Vista, then known by its codename 'Longhorn.' A preliminary version of the feature can be seen in build 4093.
On February 26, 2006, Microsoft announced the editions of Windows Vista to be released to retail and original equipment manufacturers (OEMs).[5][6] After this announcement, various technology-related outlets reported that Anytime Upgrade would enable users to upgrade to successive editions.[1][7][8]
Overview[edit]
Windows Vista version[edit]
All editions of Windows Vista, excluding Enterprise, are stored on the same retail and OEM optical media—a license key for the edition purchased determines which version is eligible to be installed.[9] When first announced, Anytime Upgrade enabled users to purchase a digital license from an online merchant to upgrade their edition of Windows Vista. Once a license had been purchased, a user's product license, billing and other information would be stored within a user's digital locker at the Windows Marketplacedigital distribution platform; this would allow a user to retain this information at an off-site location for reference purposes and to reinstall the operating system, if necessary.[10] A user could then initiate an upgrade to the edition for which the license was purchased either through components stored on the hard drive by the OEM of the personal computer, through an Anytime Upgrade DVD supplied by the OEM, or through retail installation media compatible with Anytime Upgrade.[11] If none of these options were available, Anytime Upgrade provided an option for a user to purchase a DVD online and have it delivered by mail.[2][3]
Microsoft also released retail packaging for Anytime Upgrade. The retail products were made available during the consumer launch of Windows Vista on January 30, 2007.[10] The initial version of these products included only an upgrade license, but this was later modified in May 2007 to include both a DVD and a product license.[12] In an effort to streamline the upgrade process, Microsoft announced that digital license distribution would cease on February 20, 2008; licenses purchased prior to this date would not be affected. As a result of this change, users would be required to purchase the aforementioned retail packaging in order to use Anytime Upgrade functionality[2][13] and Windows Vista Service Pack 1 omitted the option to purchase a license online.[14] DVDs for Anytime Upgrade were only produced for Windows Vista.
Anytime Upgrade in Windows Vista performs a full reinstallation of the new product edition while retaining the user's data, programs, and settings.[15] This process can take a considerable amount of time, up to a few hours.[2]
Windows 7 version[edit]
Anytime Upgrade in Windows 7 no longer performs a full reinstallation of Windows. Components for the upgraded editions are instead pre-installed directly in the operating system; a notable result of this change is that the speed of the upgrade process has been significantly increased. Microsoft stated that an upgrade should take approximately 10 minutes.[14] Anytime Upgrade also does not require physical media or additional software.[16][15] Instead, Windows 7 requires a user to purchase a license online, in a manner similar to the initial functionality that was later removed from Windows Vista starting with Service Pack 1.[14] Microsoft would also release Anytime Upgrade packaging for Windows 7 at retail. The packaging, however, would only include a license for the edition to be upgraded, as Anytime Upgrade in the operating system does not require physical media.[17]
Region availability[edit]
When first announced, Anytime Upgrade was available in the United States, Canada, EMEA, European Union, Norway, Switzerland, and Japan, with Microsoft stating that availability of the program would expand after launch of Windows Vista.[11] English version retail packaging for Anytime Upgrade was made available at the consumer launch of Windows Vista for North America and Asia-Pacific regions.[12]
In 2009, Ars Technica reported that Anytime Upgrade retail packaging for Windows 7 may only have been available in regions without broadband Internet access or where retail packaging was ineligible to be offered.[17] Anytime Upgrade was available for Windows 7 in select regions.[18]
