To "let Windows manage" the virtual memory file. Prior to XP you might gain a per cent point advantage. Today, XP, just let it manage it.
My PC has got 2 sticks of 512mb (TOTAL 1024MB AKA 1GB) but when you go ctrl + alt+ del it says commit charge 1014m / 2460m
So i am currentlty using 1014m of 2460m . But why is it saying of 2460 when i have only got 1024 has it created virtual memory because i was using my memory to its full potential?
