Yea don't you just hate that! I've seen that a lot here: Question asked----- Many chime in to help----- OP never chimes in or comes back-----
Yes must agree with you does happen a lot sometimes ends up with discussions going on for many pages and they never come back with a reply we end up closing the threads sometimes.
Personally, I thought the OP was asking if he could reuse the Win 7 OEM key on a new installation, and was answered properly in the first few replies.
