I wonder if there’s a WinDbg command just to retrieve the overall number of running processes and the overall number of running threads in the system? I am interested in the count only.
PS. I need this while doing a postmortem debugging with a full memory dump.
Not that I know, but !process 0 1 is fast enough, then just do a search for
“process:” and “thread:” in the Command window. It’s a fast enough
alternative.
Any extension that just counts needs to walk the list as well, so it won’t
be faster, it would remove the manual steps.
Hope I am wrong

You can do it with the Debugger Object Model:
0: kd> dx @$cursession.Processes.Count()
@$cursession.Processes.Count() : 0x79
0: kd> dx @$cursession.Processes.Sum(tc => tc.Threads.Count())
@$cursession.Processes.Sum(tc => tc.Threads.Count()) : 0x379
More details/examples in the documentation:
@“Scott_Noone_(OSR)” of wow, that’s pretty cool. Thanks. I wonder if there’s a tutorial on how to use that dx command? The MSDN page is quite terse.
There’s a blog post here with some introductory stuff and links to further reading:

And part of the magic here is the NatVis support, which we talked about here:

Not sure of any other tutorials
