How to create a virtual desktop with limited programs on Vista?

If you have multiple accounts on the computer you can select “Switch User” (I suppose from the Logout menu), then he can log on to his own account and do whatever he likes without interfering with yours.

I know but I want my program to run while he’s using an account but he can’t touch it and so are the files

Yeah, when you select Switch User your account is still logged in, he just gets to use his own account at the same time. After he logs out you need to make sure you also logout before you shut down though.

@Vincentt Thanks for the suggestion, I’ll try if it works :]
