A detailed technet document and step by step guides can be found here about this feature
In today’s world one of the toughest tasks for an IT administrator is to protect his computers and network from viruses, worms, Trojans and other malicious software. Although there are ranges of antivirus solutions software, firewalls and other security software, and still the client computers get affected.
Mostly this happens due to improper management of the computers. For an example, there are millions and millions of freeware (free tiny software like toolbars, funny emoticons etc.) on the internet for so many different purposes. A normal user who does not have proper understanding about the security threats involved in IT, would easily without thinking twice will download any freeware which catches his or her attention and install it on their computers. This can cause a lot of problems to the computer as well as the administrator.
By enabling AppLocker in Windows 7, you will be able to have a peace of mind as the IT guy, because users will not be able to install or use any unauthorized software applications in your organization. This will lead you to have a standardized corporate desktop which has the same software applications in all the computers (nothing more or nothing less). With this IT pro’s like you and me will really appreciate because we understand the security issues that can be caused due to unidentified software installation.
