Set up a non-administrator account, then deny permission for modifying the registry in the mandatory profile you set up to do day to day tasks on the machine and let your worries end.

You do then run into the problem that in many cases the computer will then be unusable for day-to-day tasks, because so many things in Windows want Administrator. My wife has a simple game that won't even run if you're not Administrator.

In a decade of Sys Admin, I've never seen a program that needed an administrator account to function. I would view with very jaded eyes any program that required such.
