New Version of OpenShell changes default skin?

[WC3D]

Hello,
We recently updated to the latest version of Open-Shell (4.4.190). After updating it changed the default skin from Metro to immersive. We want to force the Metro layout for all our users as this is what they've been used to for many years. I do not see a way to change the default skin via GPO. Is there a policy I'm missing or another way to change the default to Metro for all users in the domain? Thanks!!

Actually, I think I found what I was looking for in Group Policy
Skin for the Window 7 style. Set to Locked to this value -> then skin for Windows 7 style = Metro
