Do Dll Kept In Memory

I've red a tip about xp wich said:
When you close an application, Windows keep the DLL used in memory, & this slow down the system

The tip was:
Run regedit and find the location:HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows / CurrentVersion / Explorer
Then create this new sword value:AlwaysUnloadDll, and give it the value 1.

I applied this tip to my computer, and I would like to know if it really works, because it seems strange to me that microsoft would slown down voluntary people&#39;s computers for no reasons. <_<

I got this tweak added to my computer too. I personally can&#39;t tell if it made my computer faster.

So what should be the reason ?

Does anyone else tried this tweak already?

I think that if you have a large quantity of RAM (1 GB), then it might be a good Idea. if you primarily work with DV, play games, etc... it probably will slow down your computer.
