If you are sharing your computer with other people inside your home, then you might want to limit their access to your applications and files. Enabling restrictions can also increase your security and most importantly will save you from a lot of headaches. Windows 7 has a built-in tool called AppLocker that will enable you block or limit other users access to executable, Windows Installers, Scripts, a specific publisher or path.
Follow this instruction to create restrictions:
- Type in Gpedit.msc in the windows search box.
- Go to Computer Configuration
- Click Windows Settings
- Click on Security Settings
- Click on Application Control Policies
- Select AppLocker
Select one of the options Executables, Installers, or Script then create a new rule.
