windows is low on memory

No one is being hostile. Look at the big picture. How long as this myth been floating around (and has been long since been proven to be a myth)? 5 years? Longer?

If someone still thinks they are doing themselves a favor by disabling the page file, they do deserve somewhat of a slap on the wrist. That's an extremely outdated way of thinking, with absolutely no proof or fact to support it, much like if I exclaimed that pigs can fly on their own.

That being said, the OP asked how to get rid of the message. After being uncooperative with system specs, the OP finally gave some useful info. The solution is to reconfigure the system properly by enabling a page file. Problem solved.

To the OP, this isn't XP, so don't treat it as such. One of the primary reasons for using Windows 7 is the better memory management. The best tweaking advice is "leave it alone".
