Clients PC started to download and install an update, once completed it restarted the PC and now displays message saying: "Windows could not complete the installation. To install Windows on this computer, restart the installation."
While this message is displayed you have no mouse pointer and pressing any key restarts the PC to exactly the same point with the same error message being displayed again.
I've booted from a Windows 10 recovery disk, tried a Restore System point but no entries in there, tried Startup repair but didn't resolve it. Also tried going into Command Prompt and checking the hard drive and running SFC /Scannow which both didn't help.
