Open Parental Controls by clicking the Start button , clicking Control Panel, and then, under User Accounts and Family Safety, clicking Set up parental controls for any user.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the name of the person you want to prevent from using specific programs.
Under Parental Controls, click On, enforce current settings.
Click Block specific programs.
Click Person's name can only use the programs I allow.
Select the programs that you want to allow. If the program you want doesn't appear in the list, click Browse to locate the program.
