I never needed to use that option. Still, based on what I read in the documentation about Windows graphics programming, I believe that option is only applicable to video, and is prohibitively complicated to use for a password manager. Read that article https://learn.microsoft.com/en-us/windows/win32/medfound/pmp... you can’t even play DRM video from your own process, it requires a special OS component called Protected Media Path, and that process can’t run arbitrary code only components signed by Microsoft which means you can't generate DRM-ed video frames from something else with your own code.
