Hello,
Those who run Vista, and striving for memory should turn OFF DWM(
Desktop Window Manager) a.k.a "Aero" interface.
BTW: DWM turned off is the *default* setting for Windows Server 2008.
For good reason.
Why? Simply because DWM takes tremendous amounts of memory for
its eye candy. It is quite normal than DWM takes several hundreds of megabytes of RAM
and the value shown in the Task Manager is only HALF of the memory
it actually uses. Why? Because it keeps DOUBLE copies of EACH window
and each bitmap in the system. One copy in system RAM and one copy
on graphic card memory and copies back and forth.
Microsoft was well aware of this problem and they addressed it in Windows 7
which keeps only one copy of graphics and leads to 50% decrease in memory consumption
by DWM as compared to Vista.
Best regards,
Tomasz Janeczko
