Not being a computer wiz.... I do know that Vista (remember that OS?) has a "reset to factory" setting in it's restore app.

If you select it, it asks you several times "Are you sure?" because it does a complete wipe of the C: drive and then reinstalls the Vista OS to factory new condition. Any data you have is wiped clean so you should save it before you do the restore to factory.

I'm not sure if newer OS's still have that in them, but I found it to be really handy to restore a few computers my kids were using when they managed to get them cram packed full of junk.

My Dell music laptop has it.
