No luck, the same error popped up. I forgot to mention that the window header for the error message said something like this: Application Error swreg.cfexe


I also noticed that after I closed my antivirus (CA antivirus) and disconnected from the internet, the process svchost.exe run by Network Service was using up 100% of my CPU for quite a long time.
by the way, I have two processes named svchost.exe run both by Network Service one running at 8,220K (this one was at 100% CPU usage) and the other at 5,200K.
