Got in a customer's pc that he admits he tried to remove something in windows setup(trying to make it faster ) and now it is acting very weird. It starts up ok, but neither windows explorer or internet explorer will open; it loses the desktop for a second and then comes back. Same thing with control panel. If I restart in safe mode, they function fine.
I tried sfc/scannow, repair re-install of xp, disabling all startup's, etc...
I scanned for virus; it's clean. I ran spybot and found some spyware but nothing critical. I removed it ok. Still the same.
Ideas???
