Memory Problem

Hello,

I'm using Workstation Player 15.0.2 on a Win7 SP1 PC.

Host PC has 24 GB Ram.

I created a guest and reserved 16 GB memory for it. (Guest is also Win7 SP1)

When i open an application on guest, memory increases to its required value to work. (It's 3 - 5 GB physical Ram usage i see on the task manager)

The problem is, it wont decrease if i close all running applications on the guest. (Host is not running any other applications from start to end.)

I see 3 GB memory usage on guest, when the host uses 16 GB for VmWare. It decrease only when i stop vmware.

I didnt understand why memory is not adjusting itself?

Thanks for your help.
