Unable to complete updates. Undoing changes

Hi,

If you receive We couldn’t complete the updates, Undoing changes, Don’t turn off your computer message, and your Windows 10/8/7 PC is stuck in a loop, then this post may help you.

Cannot finish update restoring

Windows 10 Home Version 1903 OS build 18362.1016 Update fails repeatedly, 1. I ran the Update trouble shooter. It "fixed some things" but after rebooting Update continued to fail. 2. Following the advice on Fix: We Couldn't Complete the Updates Undoing Changes on Windows 10 - Appuals.com I successfully deleted the SoftwareDistribution Folder. Rebooted, and tried update again. Again update failed repeatedly. 3. Something I noticed on th several attempts to update is that download of update KB4574727 stops for a long time at 20% before resuming and finishing. I do not know if that is relevant or not. How do I get Windows 10 to finish updating? Thanks.

 

Windows 10: "We couldn't complete the updates, undoing changes"

I've got the same issue and following on @Arthur's suggestion, I had a look at my user SIDs in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and some of them belonged to users that no longer existed in the system (I had previously removed them).

I've removed the dummy entries (luckily there were only a couple) and the update worked.

PLEASE save yourself some trouble and backup the registry before trying that.
