You are kidding!
You haven't got it sorted out yet.
Mate I deleted the wrong key once, didn't know what it was so I had no way of finding it out. That is a while ago and nothing is wrong, I'm sure it changed something but nothing of importance to me.
My point being it really doesn't matter a great deal, messing with the registry can have debramental effects but your at your Desktop and on the Net.
Just put the 7 keys back in.
