PC with RAM 4 GB (or more)

I recently bought PC with 4 GB RAM installed. Windows Vista recognizes 4GB (as shown in Control Panel:System) but I think it uses only 3GB (as shown in Windows Task Manager). What gives?

When I upgraded to Windows 7, same problem appeared. There is a workaround. Download kernel patch, apply and see it for yourself (by inspecting total memory recognized by Windows 7)

Linux (no problemo)

#cat /proc/meminfo
MemTotal:        4117664 kB
MemFree:         2866824 kB

#uname -a
Linux surya-desktop 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:48:10 UTC 2009 i686 GNU/Linux
