I have 4 GB of RAM, but Windows still thrashes disk sometimes (especially often when an application is minimized for some time and then I activate it again). Completely stupid, because Task Manager shows 2 GB of RAM are free. Is there any way to prevent Windows swapping out program memory?

I tried setting Superfetch to cache startup files only (it helped a bit) and turning off paging file (it helped much, and worked well for me in Windows XP; but Windows Vista/Windows 7 don't allow that - it shows "low on memory" message frequently, even when I have 1 GB of RAM free.)

What can you advise me to do?
