Windows 7: Setting different default programs, for different users

Hi all!


I'm trying to set two user accounts in my computer, and would like to make them as independent as possible.

First thing was setting ownership and changing permissions for files and folders.

Then, I set allow/disallow specific programs for specific user accounts.

At the moment, my question is how to set different default programs for different users! For example, I want to use a more advanced Windows Explorer program in my administrator account, and keep Window's own Windows Explorer as default for another user.

I know how to set the default programs in Windows 7. Is there a way to do this for specific user accounts, settings different default programs for each?


Thanks!
