Windows Server 2019 group policy objects must be reprocessed even if they have not changed.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-93251	WN19-CC-000140	SV-103339r1_rule		Medium

Description
Registry entries for group policy settings can potentially be changed from the required configuration. This could occur as part of troubleshooting or by a malicious process on a compromised system. Enabling this setting and then selecting the "Process even if the Group Policy objects have not changed" option ensures the policies will be reprocessed even if none have been changed. This way, any unauthorized changes are forced to match the domain-based group policy settings again.
