Zoey,
They're seems to be an issue with the
Repair option, because it should be
trying to reinstall 29531 not 29550.
Two choices:
Pause updates til the next build or
Backup important files, docs, etc. and
do a clean install.

Hi there, so I'm tryin' to update from v 29531.1000.rs_prerelease.262026-1841 to v 29550.1000 (rs_prerelease), every time it tries to update that at the very last restart, a screen appears sayin' "Undoing changes made to your computer..." I've tried a few times to update, but this is always the outcome. Any idea on how to fix this?
THX in advance for the help. ^^

2026-03-15T17:42:16.37+00:00 Could "reset PC" with these settings be a good option too?

all your pics, docs, etc. unless you back
those up first.

Did you already try running those Copilot instructions
to try and fix the error you gave me?

2026-03-15T18:38:18.4266667+00:00 Yup, I did, but it always gives me errors. I tried to use Copilot a bit myself, and after chattin' a bit, it ended up suggesting to do a "Reset PC", just like I showed u previously, so I'll go with that. After i try that, we'll see how it goes.
