b26010 - ISSUE - Hyper-V remote console / auto lock won't hide window on Server Core

here is another example where I intentionally moved the "working window console" to the upper side of the Hyper-V console screen.

you can see the "lock screen" in the foreground, not only this causes the screen can still be read (unless you close the Hyper-V console), but also you cannot read the lock screen (logonui.exe).

So the "solution" would be to force "redrawing / freshing" the entire Hyper-V console window content when the screen lock event happens.
