- Add UserCreateSystemThread function that will signal csrss to create a new system thread.
- NtUserCreateWindowStation: Create the raw input thread and the desktop thread when the IO window station gets created.
- IntMakeHungWindowGhosted: Create the ghost system thread that will own all ghost windows.
- Let the raw input thread manage the window station of csrss.
[USERSRV] Remove system threads creating hack
- Implement SrvCreateSystemThreads
- Don't create the system threads in UserServerDllInitialization.
- NtUserSetInformationThread: Stub UserThreadUseActiveDesktop and UserThreadRestoreDesktop
- Properly mark the first thread that enters win32k belonging to csrss. At this point we assume that since gpepCSRSS isn't initialized yet, it probably is the first thread.
[WINSRV] Use NtUserSetInformationThread to set the current desktop when needed
-When csrss needs to use user32 or enter win32k, it first needs to assign the current thread to a desktop.
- Implement user32!SwitchToThisWindow by NtUserCallTwoParam TWOPARAM_ROUTINE_SWITCHTOTHISWINDOW.
- Improve user32!CloseWindow with using SetActiveWindow and ShowWindow (synchronized).

Fixes accessing nullptr / invalid handle in Window->SystemMenu
I could trigger this occasionally when moving Opera 12.18 window
in front of Spotify 1.0.29.92 window.
Fix was:
authored by Thomas Faber (Thank you!)
tested by me
reviewed by James Tabor
Added callback function that redirects calls to GreExtTextOutW that didn't went through lpk BiDi processing, calls that are from the kernel.
Completely solves JIRA issue CORE-6910.
Normally CSRSS must not be connected to any winsta or desktop by default. It should manually connect
to a winsta/desktop only when it has to do some GUI operations, and then disconnect afterwards.
[USERSRV] Temporarily hackfix the harderror dialog display to the current input desktop.
as documented in "Advanced Windows NT" by Jeffrey M. Richter (Microsoft Press),
and in https://is.muni.cz/el/1433/jaro2010/PB167/um/cv5/undocumented_CreateProcess.pdf .
[INCLUDE][SERVICES][WIN32K:NTUSER] Add an undocumented STARTF_INHERITDESKTOP flag
for the STARTUPINFO::dwFlags structure member, whose purpose is to tell Win32k
that the created handles to the window station and desktop to which the
process is connecting to, can be inherited by its child processes.
It is used when starting interactive services.
Observed via API monitoring on Windows 2003.
CORE-11933 and PR #621.
Since this API is also called from WINSRV when calling the AllocConsole() API,
it can be tested more-or-less easily. The internal helper IntResolveDesktop()
is also tested during process connection to a window station, when such process
first calls a USER32 or GDI32 function.
This is also the functionality tested by the user32:desktop apitest.
- Adjust how IntResolveDesktop() is called.
CORE-11933 and PR #621.
We are potentially going to modify the window station name to be
created or opened, by one with the format "Service-0x<luidhigh>-<luidlow>$",
in case the user provides an empty name.
Since we want to use the user-mode ObjectAttributes structure pointer so
that the Object manager can correctly perform the access checks and the
capture, we actually need to construct the new window station name in the
user memory space! This allows us then to fetch the new name in the
ObjectAttributes structure so that Ob can use it.
All of this is performed under SEH.
For NtUserOpenWindowStation(), we also need to be Windows-compatible and
detect whether user-mode gave instead the special "Service-0x00000000-00000000$"
name (observed via API monitoring) that is used when one tries to open a
window station with empty name.
CORE-11933 and PR #621.
- Remove the related hack-FIXMEs;
- Adjust NtUserGetObjectInformation() in accordance.
- Retrieve the window-station/desktop object type string in NtUserGetObjectInformation()
also from the NT Object's header.
Also simplify the UOI_FLAGS case of NtUserGetObjectInformation() by reading
the handle inheritance information directly from the OBJECT_HANDLE_INFORMATION
structure returned by ObReferenceObjectByHandle().
Fix vertical alignment and Aspect penalty; improve font penalty system; fixes for Wine tests.
This is an update of #706. See CORE-11536 for more details.
The display of the following programs is fixed:
- Total Commander 8.52 setup: font displayed too large - CORE-11620.
- Effective File Search 6.8.1 german localization text rendering issues - CORE-14378.
- Font garbage in register splash screen in Foxit Reader 7.1.5 - CORE-9767.
- Calipers-1 is not displayed correctly - CORE-14302.
- Some MSI-installers draw their dialogs too large (example: Click-N-Type Virtual Keyboard 3.03.0412) - CORE-13161.
- Irfanview 4.50: font in zoom combobox displayed too large - CORE-14396.
- Rufus: The window and controls are displayed larger than necessary - CORE-14461.
Also, improve NtUserSetWindowStationUser() capture order, make psid optional as it should (and avoid a user-mode triggered BSOD), and initialize luidUser only when everything succeeded.
An owned popup window should be hidden when its owner window was minimized.
- Add IntWinListOwnedPopups function.
- Fix ShowWindow and ShowOwnedPopups functions.
