When ever I opened up 'my computer' I seemed to be greeted with loads of drives, and yes I know that's the point, but there are some I never use and doubt I ever will.
So I had a hunt about and found some reg edits, errrr no ta as I will true to form mess that up, then I came across this.

Run it as admin and these are the before and after screen shots, and no It don't get rid of the drives, you can still access them if you have to, you just can't see them from 'my computer'
