I updated from Windows 7 Home Premium. Everything was working fine until this morning. I am able to boot to my user account and the Start screen appears. However, none of the tiles work. I can't get onto my desktop. When I try Task Manager, it will flash briefly but won't display. I can switch users, shut down, etc by using ctrl-alt-delete options. When I switch to a different user account, everything works including the Start screen. When I switch back, the Start screen doesn't work. I am now using an alternate user accounts, but I need to get back to my main account. Any advice?

TIA
Jim
