[SOLVED] Can't update Windows to 2025-02 Cumulative Update/Update Preview 23H2 KB5052094/KB5051989 (Error Code 0x800703f1)

Hello,
I'm currently dual-booting Windows 11 with Ubuntu 24.10. Today I had to login into Windows 11, and was prompted with a bunch of urgent security updates. Tried to do so and got a bunch of errors. I tried running sfc /scannow but it could not complete due to corruption errors. Dism /Online /Cleanup-Image /RestoreHealth failed as well due to corrupt registry. I can't find any option to attach files. Any help is appreciated. Thank you.

Edit: Just had to register an account, files are now attached

Update: After running the ComponentsScanner tool, I managed to successfully run both sfc /scannow and the Dism /Online /Cleanup-Image /RestoreHealth command. Rebooted, windows update ran for a while, then tried to update again, same error. So i reran everything and am reattaching the new files (since some of the errors were fixed).

Hello everyone, it's now been a few weeks and I still can't update my Windows. Maybe this got buried under all the other posts? I was hoping I wouldn't have to clean reinstall.
Thank you

Hi and welcome to Sysnative,

Upload the SCHEMA.DAT file

• Navigate to C:\Windows\System32\SMI\Store\Machine and copy the SCHEMA.DAT file to your desktop.
• Right-click on this file on your desktop and select Send To > Compressed (zipped) folder. This will create a file named SCHEMA.ZIP on your desktop.
• Attach this ZIP-file to your next reply.

Hi,

Replace the SCHEMA.DAT file

• Download the attached Schema.zip file and save it to your desktop, right-click on it and select Extract all.
• Navigate to C:\Windows\System32\SMI\Store\Machine and rename the SCHEMA.DAT file to SCHEMA.old
• Copy the SCHEMA.DAT file on your desktop into the above directory.

Afterwards reboot the system and attempt to update again. If it fails attach a new copy of the CBS logs.
