We used to support that. The WinLogon was able to run in CUI mode, CSRSS and win32k started GUI mode only on demand (ie. if any GUI API was called). Basically all the components were designed in a way that if you specified cmd.exe as a shell then the GUI would never be started unless you try to execute an application which requires it. Quitting the application would switch back to the console mode. Not sure if and why it was removed...<br>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">As we know Windows (at least till Windows 7) was designed to
be a GUI based operating system. All applications can safely assume that the
windowing subsystem is running.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">&nbsp;</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Windows/Reactos can run native applications without starting
the windowing subsystem like usetup during 1st stage setup but of course without
having access to Win32 apis as Win32k is not loaded. AFAIK win32k is designed
to be the main subsystem and is the responsible of starting the windowing
subsystem so my question is … Would be technically possible to have a striped
win32k version without the GUI code? + command line enabled winlogon, syssetup
etc.. so you can boot and run cli based applications like cmd.exe ? what other
parts of the boot process relay on having the GUI running?</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">It's more of a design curiosity question rather than a
real request</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">&nbsp;</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Regards,</span></font></p>
