Hi MSFT,

If i have the same WMI filter applying to 10x individual GPOs, does Windows evaluate that filter once or 10 times?

    Hello,

    Thank you for posting in Q&A forum.

    10 times.Windows evaluates the WMI filter each time it processes a Group Policy Object (GPO) that is linked to that filter. So if you have the same WMI filter applied to 10 individual GPOs, Windows will evaluate that filter 10 times, once for each GPO. This can have performance implications, especially if the WMI filter is complex or if there are many GPOs being processed.

    I hope the information above is helpful.

    Best Regards,

    Yanhong Liu

    Official word from MSFT via Advisory ticket is:

    "if all of group policies are having the exact same WMI filter, then, it will only run once."
