Applocker in Windows 7: Control your applications

June 18, 2009
Updated: April 14, 2022
Quick overview:

A new function in Windows 7 is called "Applocker". This replaces the "Software Restriction Guidelines" known from Vista. I would like to introduce you to this new feature.

Of course, each user must first clarify for themselves how useful this function is for them and what benefits can be derived from it. A private individual will probably use this function less frequently than the operator of an Internet café.

What does Applocker do for me?

Applocker offers the option of creating rules that prevent the execution of certain files. Applocker accesses specific properties of digitally signed files for this purpose: Publisher, product name, file name, file version. Rules can be created only for certain file versions or for certain publishers, which are then retained when the specific files are updated. It is important to note that Applocker rules determine which files may be executed. Files that are not included in the rule may not be executed! Applocker rules offer another advantage: they can be assigned in different ways. It is therefore no problem to assign rules to individual users or security groups. Assigning them to an Internet zone, to registry paths or to a computer is also no problem.

For example, you can allow the execution of all services except regedit.exe - there are no limits. Of course, you can also import or export rules.

Founded Windows Tweaks as a teenager in the 90s. His helpful PC tricks made it Germany's most visited Windows site (at the time Sandro looked like this). He then went on to write elsewhere, for example for PC-Praxis, Computer Bild and PCWorld in the USA. Microsoft also poached him from us. Now Sandro is back, finally sharing his tweaks here again. For a stress-free digital everyday life. You can reach Sandro via e-mail.
