Failed upgrade from Vista to windows 7 rtm ?

I tried to upgrade from Vista to windows 7 rtm,
everything was OK but when it start to open desktop for a first time, taskbar start to crash and reapear, it is like constantly refreshing, and it is impossible to open any program cause it shuts down immedieatly,
and taskbar and desktop continue to "refresh".
that is happening also in safe mode, only much slower.

windows doesnt repport any error, and also repair option said it does not detect any problem... ?

does anybody have similar experience, and how to solve it?

No, but you're not alone

maybe the explorer.exe is corrupted during the upgrade
i dunno, reregister some of th dlls for explorer?
otherwise, clean install next time
