My wife and I seem to be taking turns having major problems after major updates. Her machine had to be reinstalled this time - but mine has suddenly had a taskbar issue solved (became an issue after the previous fall update.
I can turn the WIFI back on - but it turns off within seconds. I've turned off power settings where I can (and hate the way these and other settings keep getting reset by updates).
So if anyone has any clues, I'd really appreciate it.
