Last night, system running fine. Woke this morning to login screen, aka MS sent an update. Boot up but the start menu is stuck. This has happened before, a simple reboot usually fixes this and its good going forward. Not this time, restart it might work but will eventually stop again. Looking at task manager I have Service Host: DCOM Server Process Launcher (6) taking up 26-30% utilization. Boot into safe mode and everything is fine however.

I don't know what was in last nights update but it appears to have really screwed up my system. The only thing I added yesterday was CPUID CPU-Z, I really don't think that is the problem. Any help would be appreciated.
