Q: How often does Group Policy
update security settings, and how
can I configure that interval?
A: By default, Group Policy is
refreshed every 90 minutes (plus a
random time period up to 30 minutes)
on domain members, but
only if Group Policy has changed.
In addition, every 960 minutes
(16 hours), security settings are
reapplied regardless of whether
any changes to Group Policy have
been made.
To modify the value of the
security refresh from the default
960 minutes, perform these steps:
- Start the registry editor
(regedit.exe).
- Navigate to the HKEY_
LOCAL_MACHINE\SOFTWARE Microsoft\Windows NT\Current
Version\Winlogon\GPExtensions {827D319E-6EAC-11D2-A4EA-
00C04F79F83A} registry subkey.
- Double-click the value
MaxNoGPOListChangesInterval
and set it to the desired number of
minutes. Click OK and close the
registry editor.
