I had a tricky problem - a virus had destroyed several functions, including File and Printer Sharing. I'd sought help - but not got any.
Then, an article in a UK computer magazine lead me to Tweaking.com. The 'Windows Repair' program here fixed most of my problems, and Shane, (Thanks, Shane) came in, and fixed the remainder.
I'm delighted to know that, in helping me, he has been able to improve Windows Repair even further.
Impressive!!
