I have a fresh install of proxmox
pve-manager/5.1-43/bdb08029 (running kernel: 4.13.13-5-pve)

I have installed memory balloon drivers
07/19/2017 61.74.104.14100

The ram reported in the OS does not match the RAM reported from the proxmox console. Any Ideas?
 
Work here on 50+ Windows VM's normaly. Have you also installed the windowsservice?
Code:
blnsvr.exe -i
 
Strange. What is the Memorydifference between host and your guest? Is the baloonservice running?
 
Q1: How did you figure that "used" in Windows?
Q2: What does "free -h" in Proxmox say?

Task manager in windows shows 3.4 GB used.

# free -h
total used free shared buff/cache available
Mem: 376G 128G 29G 149M 218G 245G

But free -h shows total for the proxmox server.

The Summary tab in the proxmox web interface for the KVM shows 10.56 being used.
 
In my original response I said I used this guide. That includes running:
blnsvr.exe -i
Yes, this install the service, but that does not mean anything that the service in Windows is really running. So go to Services scroll to balloonservice and have a look. It is running then please click on restart, is it not running (which I suspect) then start it.
