I've got a friend who I allow to borrow my computer time to time.  I guess he wants to screw around with stuff on my good ol' comp without me knowing, because he's apparently disabled some stuff.

 

First of all.. I absolutely adore Auto-Complete.  I love not having to type in everything.  He apparently disabled it.  Anyone know how I can turn it back on?  And is there a way to keep him from being able to turn it back off.

 

Also.. I want to know exactly what he's doing on it.  Is there any way to be the Big Brother of my computer and know what sites were visited, what was done there, and such?  Last thing I want is for the Feds to take my comp because he did something illegal or something.  Not that he would.  But I'm still paranoid.

 

I really don't want to do the different user accounts, because good lord knows what could happen from there.  Any suggestions?
