OK thank you
And since I don't see any problem with the ALL_USERS (without the sort order fix) I guess there is no need to apply this instead? Or which of the both reg keys do you recommend?

Hi,

Brink - This is workin on Windows Server 2016 as well?
I have a RDS/Terminal server and will apply "Restore_Windows_Photo_Viewer_ALL_USERS".
I have tested in my lab server and it worked...
