I had read that a new feature in VISTA is the ability to retrieve previous versions of files. For example, if I update and save a Word doc a few times, I read that VISTA has a feature which would enable the user to restore a previously saved version of the file.

Does this feature exist? I cannot figure out how to use it if it does. I had read to simply right-click on the file and select "restore previous version", but I have no such option for any of the files I tested.

Can someone advise on this?
