"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

set-itemproperty HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion ProgramFilesDir 'valueToPutHere' -whatif

Open in new window

This does not change anything (because of -whatif), and so can be used without caution.
