[What file is giving me this error?]

There u go thats the problem....lol....

[Network connection lost after MS updates]

Yeah Club ur right or it could be the firewall that also is blocking him from his own network connections too.... i had that happen too me all the time..

just like Tarun was meaning about Disabiling your Firewall and AV.....try that then all fails...do the restore point....or u could boot too safe mode and just delete ya Mcafee security sutie...then reboot too original mode...see what that does...

[System Restore problem]

i have too tell the truth i never heard of ERUNT...i guess since im in school for my A+ Certification i never thought about having system restore on because ill just fix my pc..but if its somethin similar too microsoft system restore it doesnt hurt too try at all......thats how you learn...from your mistakes....

[start up problems with registry]

Wouldnt Hurt Too Help too Try The Windows Recovery Console....just do a upgrade onto your Windows XP system...see what that would do...or boot too safe mode and delte ya system volume points everytime...lol...j/p

[System Restore problem]

Hmmmm what i can tell ya is too never use system restore...never ever...thats where most spyware or viruses are hidden at.....So Turn It Off and dont even think about it.....ooo yeah that link that club wrote is helpful...read that and then turn it off....
