Can one give taskmanager a higher priority when started via Ctrl-Alt-Del?

[Michael Moser]

Developing code it happens to me quite often that some process is
"running wild"and starts consuming so much CPU that even hitting
Ctrl-Alt-Del and selecting TaskManager is unable to bring up the task
manager (and hence one then can't kill that process or give it lower
priority or such).

What I find especially puzzling is this:
in several situations where the taskmanager would not show up after a
Ctrl-Alt-Del => Taskmanager I have now tried to start cmd.exe (from my
desktop icon) and then started the taskmanager from the commandline and
that DID show up! So, obviously, starting taskmanager from that
Ctrl-Alt-Del dialog absurdely enough seems to start taskmanager with a
*lower* priority that starting it from a command line... IMHO the
staskmanager should run with HIGHEST priority!

Can one change that? I.e. can one somehow configure that the
Ctrl-Alt-Del dialog starts task-manager with higher priority?

By default CAD brings up taskmgr in HIGH priority. Once an application is
launched it sets it's own default priority.

The issue isn't with taskmgr priority.

OK - but why does Taskmanager then sometimes not show up if an
application monopolizes the CPU?

Can you have answered your own question here maybe...
If an application monopolizes the CPU it "monopolizes the CPU" ?

Correct.

Because if something is looping hard enough, the task switcher never gets an
opportunity to context switch.

Timeslicing requires that interrupts can be processed which means that a
given thread must at some point issue a wait of some sort, or execute an
interruptible instruction.
