Windows 7 - How can i change the ProgramData's location?

usually in default its located in "C:\ProgramData" with 32bit/64bit and its hidden i want to change the location to another driver like i manage to change the Appdata to another driver using Regedit this is very useful for me cause every time i get a virus that will end up reformatting my OS my files stored in Appdata will be saved and it saves me a lot of time but i can't find how to change ProgramData in regedit so anyone here knows how?

Very useful post about changing the ProgramData file location. I also want to know how can we change it so that we can get rid of those viruses trying to destroy the data.

i found this in Regedit



i changed the C: to drive D: i restart my PC but nothing happen still some of my program saves to C:\ProgramData NOTE: dont try this without backing up your registry editing a registry will damage your whole system..
