This overview topic describes the process to follow when you are planning to deploy AppLocker rules.

When you are determining how many Group Policy Objects (GPOs) to create when you 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 Software Restriction Policies (SRP) policies and AppLocker policies in the same GPO
-   GPO naming conventions
-   GPO size limits

>**Note:**  There is no default limit on the number of AppLocker rules that you can create. However, in Windows Server 2008 R2, GPOs have a 2 MB size limit for performance. In subsequent versions, that limit is raised to 100 MB.
