memory

I'm running Windows Server 2008 Datacenter Service Pack 2 on a VM Ware instance with 10Gb ram allocated. I'm not running IIS or SQL Server. Under 'normal' conditions, the machine uses ~5.5Gb of memory.

However, when I login to the server through remote desktop, the memory usage slowly climbs up to 9.8Gb of memory in use. After several minutes the memory slowly creeps back down to the 5.5Gb mark.

I've tried killing all the processes associated with my login, on login, barring the taskmanager without success, and I can't see any process that is growing in memory usage when the memory is increasing.

I'm assuming this is some system level cache that is growing / shrinking... but why is it doing this?
