System will not resize GUI and controls according to DPI scaling. You must do this manually. For example
; current value of primary monitor DPI is stored in the registry: ; HKCU\Control Panel\Desktop\WindowMetrics, AppliedDPI ; need to relogin after DPI changed to update this value $Scale = RegRead("HKCU\Control Panel\Desktop\WindowMetrics", "AppliedDPI") / 96 DllCall("User32.dll", "bool", "SetProcessDPIAware") GUICreate("DPI test", 200 * $Scale, 100 * $Scale) GUICtrlCreateButton("test button text", 10 * $Scale, 10 * $Scale, 80 * $Scale, 25 * $Scale) GUICtrlCreateCombo("test combo text", 10 * $Scale, 40 * $Scale, 100 * $Scale, 25 * $Scale) GUICtrlCreateLabel("test label text", 10 * $Scale, 70 * $Scale, 70 * $Scale, 25 * $Scale) GUISetState() Do Until GUIGetMsg() = -3  

This is possible if to use WinAPI
See example in help file for
_WinAPI_DragQueryFileEx()

It looks like the functions _GUICtrlMenu_GetItemEnabled and _GUICtrlMenu_GetItemDisabled should use $MFS_DISABLED
