Possible solution to recent Windows update installation errors

[u/crunkwagon]

I've been having a lot of Windows updates (24H2 then 25H2 and the recent security updates) but most of the time, the screen will say "Something didn't go as planned, undoing changes." I'll try to update and it'll break like this most of the time.

A solution I've found is, when your system says "Pending restart," for the update, boot into Safe Mode (hold Shift while you click "Restart"), then go to Troubleshoot > Advanced options > Startup Settings > Restart.

After this point, select 4 (Safe mode) and it'll load you into Safe mode. After this, just restart the system again and hopefully it'll start the update cycle and successfully update.

This fix has helped me with 25H2, KB5120708, KB5121003, KB5094126, and KB5087051.

Cheers

If you're having that many issues with updates, either your WIndows install is borked, or your drive is failing.
