## 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.
v6 comboboxes default to displaying up to 30entries and
give a bad user experience in LiveCD
where we usually have low vertical screen resolution.
Therefore limit the height of the expanded boxes to
bring us close to how they were drawn before 0.4.12-dev-882-g
e3e173ffaa
Adding CBS_NOINTEGRALHEIGHT gives similar result for both:
comctl32 v5 and v6 comboboxes.
Similar commit for bootcd CORE-16252
went into 0.4.13-dev-740-g

- Transform TryToStartShell() into a StartProcess() function whose aim
is just to start processes, since there is no extra initialization needed
for starting a shell process.
- Modify StartInstaller() to call StartProcess() for starting the ReactOS GUI
installer found on the installation media, from a path automatically expanded
depending on the ambient CPU architecture.
