This preference (DisableOSUpgrade) prevents the upgrade to Windows 10

Windows, Windows 10

Windows users who run Windows 7 or Windows 8 on their devices have for the most part probably run into offers to upgrade to Windows 10 by now.

There are several solutions to prevent the upgrade from happening, but it seems difficult to block it permanently.

The effort required may increase when the updates of the January 2016 Patch Day are released, as Microsoft announced previously that it would make the upgrade to Windows 10 an important update in Windows Update.

Quite a few options are available to prevent the Windows 10 upgrade on devices running earlier versions of Windows.

Common methods include researching all updates for Windows before installing them on the system, and running a third-party software like GWX Control Panel which does a great job at informing you and blocking update attempts.


It is interesting to note that Microsoft has made the information available with the release of Windows 10 but that many users don't know about these options.

Windows users have two options to block the upgrade to Windows 10. First, by using the Group Policy (only available on Pro, Business and Enterprise editions).

  1. Tap on the Windows-key, type gpedit.msc and hit enter.
  2. Navigate to the following location: Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Update
  3. Double-click on Turn off the upgrade to the latest version of Windows through Windows Update.
  4. Enable the policy.

To undo the change, set the policy to disabled.

If you don't have access to the Group Policy Editor, or prefer using the Registry, do the following:

  1. Tap on the Windows-key, type regedit and hit enter.
  2. Confirm the UAC prompt if it is displayed.
  3. Navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
  4. Check if the preference DisableOSUpgrade exists.
  5. If not, right-click on WindowsUpdate and select New > Dword (32-bit) Value.
  6. Name it DisableOSUpgrade.
  7. Double-click the preference.
  8. Set its value to 1.

To undo the change, delete the key or set it to 0.

Update: One additional Registry preference came to light recently that, when combined with the one described in this article, should prevent the upgrade to Windows 10 on all home and business machines running Windows 7 or 8.

  1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\GWX
  2. Right-click on GWX and select New > Dword (32-bit) Value.
  3. Name it DisableGWX
  4. Double-click it and set its value to 1.

To hide the Get Windows 10 app

Microsoft reveals in a Knowledgebase article how to hide the Get Windows 10 app on older versions of Windows.

The company notes that the app is not displayed on certain systems automatically, and that users don't need to do anything in this case.

  1. Computer joined a domain.
  2. Computer is managed through MDM.
  3. The computer runs: Any Enterprise version of Windows, any Windows RT version, any Windows Embedded version.

A Registry key is provided that system administrators and users can set to block the Get Windows 10 application.

  1. Open the Registry Editor again.
  2. Navigate to the key: HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade
  3. Right-click on OSUpgrade and select new > Dword (32-bit) Value.
  4. Name it ReservationsAllowed.
  5. Double-click the preference and set its value to 0.

Delete the key if you want to undo the change.

It makes sense to implement these preferences on devices running earlier versions of Windows if those devices should not be upgraded to Windows 10. Obviously, this should not be the only options and a program like GWX Control Panel or manually verifying all updates before they are installed are proper options to make sure nothing slips by.

    What mental age of reader are you targeting with the first sentence? 10?

    Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.

    If your paymaster Microsoft permits it, of course.

    5. Rufus
    6. Ventoy

    PS. I hate reading these “SEO optimized” articles.

      I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.

    bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.

    ps…. time travelling?

    Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.

    I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:

    1) Too young to remember a time before W10 and W11 (doesn’t know better)

    2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)

    3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””

    4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows

    5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss

    Obviously that doesn’t cover everyone, there’s also the category that:

    6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now

    Have I missed any group off this list?

    1. Heinz Strunk said on September 19, 2023 at 3:57 pm

      You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.

      Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.

    Microsoft has removed KB5029351 update

    1. EP said on August 24, 2023 at 9:21 pm

      only from windows update though
      KB5029351 is still available from the ms update catalog site

  7. Anonymous said on August 24, 2023 at 11:05 pm

    1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.

    2. I have installed it in a 11 years old computer, and no problems at all.

    3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.

    This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
    Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.

    Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.

    Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.

    1. John G. said on August 25, 2023 at 12:08 pm

      Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

    While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.

    My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
