Updated: June 21, 2012

Applies To: Windows 7, Windows 8, Windows Server 2008 R2, Windows Server 2012

This overview topic describes the process for planning to deploy AppLocker rules.

You should review the following topics to learn how to structure AppLocker rules for the targeted business groups in your organization:

When determining how many Group Policy Objects (GPOs) to create to apply an AppLocker policy in your organization, you should consider the following:

  • Whether you are creating new GPOs or using existing GPOs

  • Whether you are implementing both Software Restriction Policies (SRP) policies and AppLocker policies in the same GPO

  • GPO naming conventions

  • GPO size limits


There is no default limit on the number of AppLocker rules that you can create. However, GPOs have a 2 MB size limit for performance. In Windows Server 2012 and Windows 8, that limit is raised to 100 MB.

After you have determined your Group Policy structure and rule enforcement, record your findings as explained in Document Group Policy Structure and AppLocker Rule Enforcement.
