Does anyone know what the definition [[[Delete all values]]] means under Policy Setting column of Policy Viewer tool?

More specifically:

grey_field

If i navigate through registry to the aforementioned path, I see that there are literally no values under DenyDeviceClasses registry key besides the (Default) REG_SZ (value not set) that exists under any Key in Windows registry, and the 1 REG_SZ that I manually added after tool's recommendation (next line).

To be more clear, the key DenyDeviceClasses didn't even exist before I manually add it as well.

registry

So, my question is, since the DenyDeviceClasses key didn't exist before I manually add it after tool's recommendation, why this line appears as there is a value difference between the current Effective state and the Baseline's recommendation (Grey Box next to [[[Delete all values]]] field under Effective State column). I even manually removed DenyDeviceClasses registry key completely and re-run the comparison, still same grey box appears in this line.

Any clarification on this would be greatly appreciated.

    Hello

    Thank you for posting in Q&A forum.

    Registry DenyDeviceClasses related with Administrative Templates policy.

    You can find this group policy by below path:

    Computer Configuration > Administrative Templates > System > Device Installation > Device Installation Restrictions > Allow installation of devices that match any of these device IDs

    You can don't set any value of this policy if you don't want to see this registry.
