There's been a brief discussion about RegShot (to show before & after registry changes), RegMon, InCtrl, & UndoReg1.46 in the IE forum at <post#=278696>post 278696</post#>, <post#=278750>post 278750</post#>, & <post#=279635>post 279635</post#>.

I'm posting it here for posterity. InCtrl is no longer free. PC Magazine now requires a subscription for their downloads.
