Found this piece of software this morning and decided to give it a try.
It actually serves two purposes as far as I'm concerned;
1. To check the presence and general availability of your existing system restore points.
2. And this one is really cool, supports the mounting of and accessing folders and files within your restore points for the purpose of perhaps recovering a particular file that seems to have disappeared for whatever reason.
If you would like to give it a try it can be found here.
