Thank-you for taking the time out to compile your findings and write the article.

Nice article, I noticed one issue. You refer to the program you're running as process monitor in the article but I believe it is actually Process Explorer. Lost some time tracking down that issue since I haven't used either one in a long time. If you want to throw in a link, it is here on the TechNet site. I also noticed that the interface has changed in the new version.

I've just installed the latest version of Process Monitor 2.96 and cannot find an option to show the system information as you mention. Would you perhaps elaborate for us as there is no View option in this version of the program.

I linked the correct program in my post above.

I believe there's an error in the article, circa 4,700,000 K is not 4.7MB, it's 4.7GB.


"The Available counter will show how many KB are available to the host;400 MB is probably as low as you would want to see it. The image above shows ~4.7 MB in the Available counter"

Can you clarify that current should be less than available?

See mine...

Hi, great article! I have a doubt when you say:
When the Current counter is larger than your Available counter it indicates that you are paging to disk
Isn´t part of the current memory already used by my process, that's why the available memory is lower? And maybe my process is not swapping to disk?

Thanks,
