HANDLE, THREAD, PROCESS System Limits

[Guest neilsolent]

How can I look up the absolute HANDLE, THREAD and PROCESS limits of

Windows? (By this, I mean the maximum numbers that can ever be reached

in the "Totals" box on the Performance panel of Task Manager).

 

Ideally I would like to get these theoretical maximum values from a

script - so I need something like a registry key, or perfmon counter

or WMI object.

 

Many thanks for your time!

Process Monitor is an advanced monitoring tool for Windows that shows

real-time file system, Registry and process/thread activity:

Thanks for that Carey, looks like a good tool.

But do you know the answer to the question ?

I have tested and it seems that the upper handle limit on W2003 is

around 1.3 million. I've no idea why, where this is set, or wether it

can be configured. I have even less idea about the limiting number of

processes and threads!
