My life, My work, Its always an Adventure

This is very weird... I installed Windows 7 RTM in a Virtual Environment. I gave this machine 512 MB RAM. It worked perfectly and after a fresh installation the memory usage was about 250 MB. (About 50 MB more for the x64 bit Version). I thought, WOW this is really good.

So I decided to install Windows 7 x64 bit (because I have 4 GB RAM) and after the installation it used 800 MB!!! oO Ok, I started to stop some services and uninstall unnecessary Programs like Windows Search or the Superfetch Service. Also the Themes Services got stopped... Now I could reduce the memory usage after a reboot to about 550 MB. But it is still more then in the Virtual Environment.

So if someone has an Idea why it is that much more then in an Virtual Environment, then let me know. Because i need the rest of Memory (4 GB - the 300 MB as in VM) for other Virtual PCs.
