Locked form regions

Supported on SUPPORTED_Windows7 (defined in the Windows templates)

5568.1000

What it does

This policy setting allows you to configure adjoining form regions to be always expanded. If you enable this policy setting, you may enter the adjoining form region name as the Value name and the Value data as "1" (without quotes). This ensures that users see the whole adjoining form region and cannot collapse it. This works for both Explorer and Inspector. If you disable or do not configure this policy setting, adjoining form regions are not expanded.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: L_empty76
