GPO Filtering Not Applied (Unknown Reason): 3 Ways to Fix it

The Group Policy is an advanced tool that requires a bit of understanding before use. The Group Policy filtering not applied (unknown reason) is one of the problems users complain about. It indicates a concern with the target object you are trying to apply your GPO.

Moreover, a series of factors may be responsible for this error on your Group Policy, causing it not to apply your GPO (Group Policy Object) security or WMI filtering. Nonetheless, we’ll take you through how to fix the problem and get it working again.

What could be the causes of GPO not being applied?

Local Group Policy Filtering: not applied can occur in numerous cases – for example, while implementing a security or WMI filtering.

However, a factor that causes the GPO not to be applied is incorrectly assigning your security groups. Other notable causes are:

• Configuration issues in the Group Policy: Users need to allow permission for some options in the GPO delegation. So, the Group Policy filtering may not apply if these options are not enabled.
• GPO Setting is for the wrong object type: Applying filters to a group object needs you to specify the object type, and a mistake with that may result in filtering errors.
• Group Policy Object (GPO) not linked to any Active Directory network: The GPO not applied error may occur if the GPO is not linked to any AD network. You can check out how to enable Active Directory users and computers in Windows 11 to set up your AD.
