If you have access to run non-standard programs then you can probably get permission to take or have IT take a fresh system image after a clean install plus your additional programs. Reinstall would then just be a drive image restore including your addons.

I'm spoiled in the *nix world, I can rebuild an install in about the same time it takes a drive image restore to run. Long as the user data is backed up; the machine can be rebuilt on a whim. (not that this stops me from trying to identify and solve issues before resorting to reinstall)
