Going to go another week with these registry tweaks in the cluster at work to vet them and then I'll update my blog for all to see. But I'm reducing the memory needs of my 2008/2013 R2 servers so far by 45% after just about 22 registry tweaks while not causing instability or security issues. Talk about Microsoft bloat in the registry hive, SMH! ... scoured the internet for weeks finding everything under the sun to do to tweak the snot out of Windows Server.
Here are some pictures, Can you all do this?
I'm able to constantly reduce the memory allocated to these VM's; why give it RAM if it doesn't need it, even on load!

....Next I made reduce the CPU's....but that will take monitoring and future-casting with vCOPS.
Wonder what the performance will be like once I move the servers to there own vlan and off the 60% load /23 subnet and putting them on a /25 subnet.
Primary DC (VM): Forest Masters, DNS, DHCP, FTP, and GPM:
Terminal Server (VM) (6 active users on server as of screenie - typical applications: Outlook, Excel, Syteline ERP)
Print Server (VM) (62 printers, mid-morning load - shipping/receiving print no-stop from 5 am til 9 am)
