Yep all seems to be working, Custom Device Skin is working on my Win8 Ent as well. Thanks a bunch 
@Tom, Regarding Custom Device Skin
The first time you load a project (and don’t switch to a different view) and go to custom device you can change it just fine, it only fails when you CTRL+R and try changing to custom device and/or switch views then try custom device.
Yes, I noticed that too about Custom Skins. We are looking at it now. Thanks for testing and the report.
