Almost 50% memory usage

Specs: Windows 7, 2.6 GHz x 4 Cores
Hi guys! Ive noticed that My memory usage doesnt go down from 1.6 GB out of 4 GB even with no applications running.
Physical Memory
Total: 4095
Cached: 2247
Available: 2451
Free: 255
Compared to my 3% CPU usage this looks really bad ;d I closed the sidebar, bitcomet, skype, browser and most processes that use over 10 000 K of memory but it goes down only to 1.3 GB. Is this normal? My OS is Windows 7 Ultimate.
P.S. I have only one account on this computer.

Those numbers actually look quite good. If there is a problem it isn't shown here.
Memory usage in Windows is highly dynamic. Usage will vary a great deal according to how much memory is available and what processes are doing. Usage when the system is doing nothing may seem high, but that is only because there is currently nothing better to do with the memory. Windows hates free memory and will always try to find some use for as much as possible, even if it is only something of trivial value. Free memory is wasted memory. When running a large application the usage of inactive processes and services will be cut back to meet the demand.

Be aware that most of the memory labeled as "Available" is not free but is actually in use. In a modern OS this is not a contradiction. All of available memory, except for the 255 MB labeled as free, is actually in use.

The 255 MB free is only that high because an application was probably closed recently and Windows has not yet found a use for it. Assuming you haven't disabled this feature, Superfetch will soon try to fill this with something useful.

It may be difficult to understand but Windows actually manages memory very well. The next version will probably be even better.

Vista and Seven both cache your frequently used programs in memory, but 50% does sound quite high. My main system also has 4GB of RAM, but W7 Ultimate x64 only needs 15% of it at the desktop.

Review your msconfig. If you have an HP printer or scanner, uninstall or disable as much HP bloatware as you can. HP writes some amazingly crappy software.

Most Cyberlink, Adobe, HP, update/regiseration service for any software, and Creative (except the main driver) can be disabled.
