when I start up my computer I get an error saying:
Userinit.exe - Bad Image
C:\windows\system32\USERENV.dll is either not designed to run on windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support
Alternately the error will sometimes say C:\system32\RpcRtRemote.dll. Eventually the screen will go black and the bottom right corner will say "This copy of windows is not genuine". At no point do I actually get to my desktop where I have access to my icons or the start menu or anything, even in safe mode, so I'm not sure how I would go about running system restore or scanning for a virus or anything. Any suggestions?
