When I change a Group Policy, changes are stored in the registry.
F.e.: To deny apps from using the camera (for all users)
- Start gpedit.msc
- Navigate to Computer Configuration > Administrative Templates > Windows Components > APP privacy
- Change to "Enabled" and set option to "Force deny"
This will create following two registry-keys
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy Objects\[b]{B454C6DA-0F21-452E-BADF-9167068901C8}Machine[/b]\Software\Policies\Microsoft\Windows\AppPrivacy -> LetAppsAccessCamera
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy Objects\[b]{B454C6DA-0F21-452E-BADF-9167068901C8}User[/b] <- no values added here
Portion: {B454C6DA-0F21-452E-BADF-9167068901C8} seems to be a randomly created ID per system or user???
Also another key is created, but this is not shown in Process Monitor:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\AppPrivacy -> LetAppsAccessCamera
1. What I would like to know is how I can set Group Policy option like the ones in APP Privacy through registry changes only?
2. How to determine the ID that is created (f.e.: {B454C6DA-0F21-452E-BADF-9167068901C8}) as I can't find any info about it on internet.
