Symptom

In Taskmanager there is almost no "free memory", although there ought to be plenty

Cause

Vista Memory Management uses physical memory (RAM) different than predecessors

Solution

In short: if you see only a few megabytes free in your Taskmanager - Performance view, although hardly any applications are opened, it's not a bug - Vista is not devouring all this RAM, it just uses it differently.

In short:

While former Windows Versions "used" available RAM for Applications when needed and (hopefully) freed it upon closing applications, Vista "SuperFetch" Technology uses all of your RAM for Memory Management (like a Cache) and therefore does not show much free RAM. However, if you look at the graphics or the Ressourcemonitor, you can pretty much figure out, how much your system uses.
