Sigh.
I didn't say I cared about how much RAM I have free.
I care about unnecessary hard drive usage.
I don't want Windows to try and guess what I want open and then load it up. Maybe I do usually load such and such, but maybe today I want to load something else - I don't want Windows to second guess me.
If I want to load Outlook? I click on it, it loads in a blink of an eye, I have SSD.
It is smoke and mirrors - Windows 7 and Vista cannot load apps any quicker than XP does because they can't spin your hard drive faster. There are of course a few small system tray apps I load automatically every time I start Windows and they all load in a combined time of about one second, and again superfetch is not needed.
Question!
Have you tried Windows 7 on your system?
