Update is fine, until it isn’t
I have updated 14 machines to the latest version of Windows. 13 went fine, with no problems. The 14th - an Acer desktop, ended up in a nasty loop where it kept restarting, booted to a black screen, and then rebooted.
After forcing it to crash to get to system restore, was unable to roll back to previous version. The only option was to reset windows which took me back to 1709 losing all of my installed programs. A second attempt fared no better. Microsoft support for this issue has proved non existant. The workaround is a registry hack to prevent automatic updates, but certainly not ideal.
So where can i go for support when a Microsoft update borks a PC?
