The static cache for group policy settings should be cleared when GP settings change #5804
Description
Activity
If I recall registering RegisterGPNotification requires administrative rights in the past. You could register but you wont get any events without admin rights.
Docs don't mention about admin rights but suggest also use WM_SETTINGCHANGE message.
Ilya (@iSazonov) I had script while ago that I needed to listen GP events and I could never get it to receive those events in PowerShell 4. WM_SETTINGCHANGE required a window based app (GUI) to listen for that message.
Greg Zimmerman (@thezim) Thanks for clarify!

Open the issue per the ask from #5791 (comment):
We use a static concurrent dictionary
s_cachedPoliciesFromRegistryas a cache for group policy settings retrieved from the registry (inUtils.cs).We should register for GP change notification using
RegisterGPNotification, so that we can clear the cache when GP changes.
