Win10 1803 Update Woes

Hello

I have 3 separate laptops from different manufacturers where the latest 1803 update has left them with a black desktop and Windows/Search buttons that no longer work. In 2 cases I have managed to restore the desktop and any prog shortcuts on there work OK in most cases. 1 CAD program has a problem with a missing licence.

None of the machines have restore points available and I can't reinstall Windows (in place) due to a licence problem.

On first boot after the updates, there was a new option on the screen "Windows Rollback" but this didn't do anything, I has to use the "Use a different OS" option which showed 2 Win10 installations.

Anyone else had same problem and (hopefully) found a solution ? Otherwise I will have to start from scratch and reinstall

Thanks in advance

After deleting a new account that I had created as 1 test, I tried rolling back to the previous version but that failed and told me to try a Reset instead. (Have yet to try that)

Now the PC is refusing to accept the passwords for the existing user acccount and the local admin account, both of these were working before I deleted the new user account

Attached is a pic of the error message I received when I started setup.exe as a New Task, I had identical messages on 2 machines so far. (Error validating product key by installation program )

I have also had a "sihoste.exe Unknown hard error" message on both machines several time.

Looks like I will have to do a fresh install on this first machine but it would be nice to solve this problem on the other machines

Thanks

This was a neighbour's machine that updated automatically.

I wasn't aware of that rescue disk so downloaded it and tried the HD diagnostic which found nothing (as did the WD software) so will wipe the disk and try reinstalling from scratch

I also tried to reverting to the previous version on a 2nd machine and that didn't work either so I believe there is something really wrong with this automatic upgrade. I had manually forced the upgrade on my 2 PCs without any problems.

Re-install in my clients case was the only option that worked
