Vista - Create virtual drive to store user files...

Hey Guys,
Im rebuilding someones laptop and since they are always managing to break it im installing quite a bit of security so they couldn't break it even if they wanted to.

I have a problem though, im going to hide the C:\ so they dont decide to have some fun with the windows directory or something. Now by hide, i dont mean the attribute im actually going to make the drive invisible to them and it will also prevent direct access. They can still use the things on there, they just cant open it themselves. For example typing "C:\windows\cmd.exe" into an IE bar will be disallowed but typing cmd into the start menu will be allowed.

However, my problem is that the user folder is on the C:\. Now i noticed in my school they create a separate drive for personal files and that drive is not hidden. I want to do that, but i dont know how to;

• Create a virtual disk.
• Change the user personal file location

Any help on this would be nice and I will rep you
Thanks
