- CM_Locate_DevNodeW expects a Device Instance ID as second argument,
so it cannot be used for converting a Hardware ID.
- Use SetupAPI functions here instead, as documented in:
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-enumdisplaydevicesw
- Now our desk.cpl passes correct identifier to CPL extensions,
such as deskadp and deskmon, so clicking on "Properties" in the
advanced display properties now works in Windows XP.
- Also fix copypasta in DisplayAdvancedSettings that affected applet
built with MSVC - deskadp extension was loaded twice.
- Also fix magic flag value for EDD_GET_DEVICE_INTERFACE_NAME.
## Purpose
[SYSDM]
- When closing System Properties page, log show
(win32ss/user/ntuser/windc.c:749) err: [00060138] GetDC() without ReleaseDC()!
because GetDC() is called (multiple times) without properly calling ReleaseDC() as required in order to release a device context.
- This module also lacks some error management in case null DC are provided (on error).
- LiveCD Userinit, based on SYSDM is affected too.
[DESK]
- Fix missing ReleaseDC related to the spectrum (color depth)
## Proposed changes
- ReleaseDC() added.
- Error management in case of null DC.
- Overall alignement of LiveCD Userinit and SYSDM.
