So my fulltime rig at the moment is my Aspire One. I know its not much, but it does the job, and lasts 5 hours on a charge. I recently decided to dual-boot XP with Vista. After weeks of trying to lower memory usage by disabling services or vliting and install, I tried Windows 7. Windows 7 always had low mem usage on my desktop and I heard good things so I figured it would give me XP-like RAM usage. No, this didn't work. Both Vista and 7 take 60% of my RAM idling. 80%+ while browsing the net, this is with services disabled(Superfetch, Windows Search). XP uses only 400MB of RAM with lots of stuff open. What is up here? How can I lower the memory usage? The Aspire One is the 1GB of Ram model.
