Win11 update uninstallation failed 0x800f0825

To resolve error code 0x800f0825 when uninstalling update KB5063878 on Windows 11 24H2, follow these five steps:

(1) Disable Windows Sandbox via Control Panel to remove dependency conflicts;

(2) Use Command Prompt with wusa /uninstall /kb:5063878 to attempt manual removal;

(3) Run Windows Update Troubleshooter from the Settings > Troubleshoot menu to fix update-related issues;

(4) Repair system files using DISM /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow; and

(5) Check registry settings for app pool recycling that may interfere with update removal during off-peak hours.

In the command prompt, type the following command and press Enter:

wusa /uninstall /kb:5063878

I also came across this issue when uninstalling the update. Sorry I do not have a solution for it. So far, i have not encountered any issues with the new KB5063878 update but i have paused the update for now.

I figured out the reason causing error 0x800F0825, at least in my case.

If you have Windows Sandbox enabled, that is the reason. You have to disable it in the "Turn Windows Features on and off" menu, reboot, then you'll be able to uninstall KB5063878.

In the CBS.log when the error happens there would be lines like this:

2025-08-23 13:09:12, Error CBS Container base layer depends on LCU version greater than '10.0.26100.4946'.: 800f0825 [Error,Facility=(000f),Code=2085 (0x0825)]

The "Container base layer" it's talking about has to do with the Windows Sandbox. Disabling the feature removes that dependency allowing the uninstall to proceed.

You can turn the feature back on after uninstalling the update.
