2026 Preview update (KB5077241) (26200.7922) couldn't install

Question

I have an update that needs to be installed, and I have tried numerous times to complete it, but it keeps giving me the message to try again. It is 2026.02 Preview Update KB5077241 (26200.7922)

Answer 1

KB5077241 is an optional preview update, it is basically an early February beta release of the March update.

The optional preview updates can be hard to install sometimes, may contain bugs and there is no need to install the optional preview updates.

There are some reports of that preview update changing the Windows UI language and even uninstalling the update does not resolve the problem.

If that update is continually failing, below that update is a switch to 'Get the latest updates as soon as they are released', disable that option and restart your PC, that will stop the optional update continually trying to install and wait for the full March update to be released.

Answer 2

KB5077241 (build 26200.7922) is a Windows 11 Insider Preview update. There is a known situation where systems on the Release Preview (RP) channel unexpectedly start downloading a Beta channel build like 26200.7922 and then fail or get stuck.

A moderator-confirmed workaround is:

1. Before the faulty Beta update completes, remove the Insider configuration so the device stops trying to install that build.
   • Open Registry Editor and delete the WindowsSelfHost key (this is what the moderator did to exit the Insider program).
   • Restart the PC.
2. Clear the partially downloaded update payload:
   • Pause Windows Update in Settings.
   • Go to C:\Windows\SoftwareDistribution\Download and delete its contents.
   • Restart the PC again.
3. Resume Windows Update and let it check again.
   • The system should now download a different, appropriate build (for example, 26200.7922 was replaced in the moderator’s case by 26200.7922’s successor for RP).

If continued Insider participation is desired, re-link the device to the desired channel (such as Release Preview) after the issue is fixed and that channel is available again.

Note: Editing the registry and deleting update cache folders can affect system behavior if done incorrectly. Back up important data first and only change the keys and folders mentioned.

Just went to Windows Update and it is downloading a Beta Channel Release. I have never changed to Beta Channel so why in the world is it downloading Beta???????
