Fixes the window borders on classic theme windows when DWM is active from spilling over to other monitors.
It occurred with DWM on because DWM is only compatible with manual window clipping via SetWindowRgn, like UxTheme uses, and not the special override that Win32k applies for rendering maximized windows with default (classic) frames. This simply makes all windows use classic theme frames.
Command Prompt windows will still not be properly clipped, however this issue already happened on older
versions of Windows. Technically, there is a timing issue with Windhawk injecting into console windows,
so rarely they may be affected. For consistency, I manually excluded conhost.exe
.
