Problem updating to the latest preview insider channel build

Zoey 10

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. ^^

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.

Could "reset PC" with these settings be a good option too?

You could try that, but you would lose

all your pics, docs, etc. unless you back

those up first.

If you have any 3rd party Antivirus uninstall it

and try the update again.

Morning, so I don't have any 3rd party AV. I searched a bit yesterday in the event viewer, and an error was noted, and unfortunately I can't find the exact error that was noted, but it was something related to maybe a disc corruption (?) so it may be related to that. Sorry if the information is not so clear, but my bad memory makes it hard to remember.edit: I found it; this is what it says

"Initiating system store corruption detection and repair. Detection Only: 0, Automatically Triggered: 0"

Right click Start, Device Manager and

make sure there aren't any yellow triangles

showing. Or go to the manufacturer's web

site for driver support and updates.

That's a very generic error.

Make sure all your drivers are up to date

including BIOS and try the update again.

If it fails again, delete the Windows/SoftwareDistribution/Download

folder and try the update again.

I can't find it but if my memory doesn't betray me, it should be 0xc1900101

My update history says the failing code was x0c100101. (I see copy & paste doesn't work here).
