MahApps.Metro: The property IsWindows10OrHigher in BorderlessWindowBehavior throws exception

What steps will reproduce this issue?

The property IsWindows10OrHigher in MahApps.Metro/Behaviours/BorderlessWindowBehavior.cs introduced in https://github.com/MahApps/MahApps.Metro/commit/fe7dd828dbc945a705f10be67983a75a147328fc#diff-783a1e5d5018be41e08311212094178e is causing an exception on Windows 10 with Aniversary update. Seems that there are problems with WMI (even when running as administrator…)
