Windows 7 AppLocker

Windows 7 introduces a feature called AppLocker. Type gpedit.msc into your search bar and press enter. Then go to:

• Computer Configuration
• Windows Settings
• Security Settings
• Application Control Policies
• AppLocker

You can define policies based on Executables, Windows Installers, and scripts and select witch groups the rule will apply to.
Also you can  choose to create rules based on a publisher (the program needs to be signed), program path, or file hash (usually a good choice if the program isn’t signed).
Go ahead and play with it. And let me know if you like it. I do.
