Small Proxmox server

I am running a small form factor as a Proxmox server with some services, i need to run a couple of windows virtual machines on this server (i5 vPro with 16gb) i ve installed tiny10 as a trial but it think its so tripped down of essentials that i keep getting class errors for simple tasks.

Long story short, i need to run 2 "as light as possible" windows VM's on this machine...any help?

Thanks in advance.
