Error: We couldn’t complete the updates, Undoing changes. Don’t turn off your computer.

Fixed all my problems! I bought a Mac Kiss off MS. Thanks to all on here for your help and good luck!

Having the exact same problem.

Had this problem for weeks now, when I go to settings and try to update windows it doesn't connect and says error but when I go to the error details it is blank. Help! It had been undoing the changes for the past 3 hours and is very frustrating
