[wix-users] failing to elevate privileges on Win 10 - WiX 3.9r2

There are two Microsoft support configurations.

1) UAC and File Virtualization enabled;
2) UAC and File Virtualization disabled;

Unfortunately, it is common to see UAC disabled and File Virtualization enabled.  And I've even seen UAC enabled and File Virtualization disabled.

If File Virtualization is not able to start, there will be logging in the Event Viewer.  Of course, it's even easier just to check the registry entry as above.

How should he check for whether FileVirtualization is disabled?
