Hi Mark,

I think you missed part of the thread.

If you show VMSize in Task Manager it does _NOT_ show the full VMSize. As per Vlad's reply only when using SysInternals's Process Explorer you can see the real thing.

Just try for yourself with an app using 800 threads.

I don't think it does, but if you are talking about total memory: that
should be included in the memory figures of taskman, AFAIK. That it
looks like taskmanager is not reporting all memory, is because the
memory column in taskmanager shows the current workingset (ie the
current size of pages paged into physical memory), and not the total
memory usage in virtual memory (to show that you need to add the column
VM size (or maybe assigned size).
