I was asked how to set the pagefile on a Hyper-V Server, considering the GUI doesn't exist. After some research, I came on these commands.
Here are the Hyper-V PageFile Commands:
wmic pagefile get /format:list
Turn Off Automatic Configuration:
wmic computersystem set AutomaticManagedPagefile=False
wmic pagefileset set initialsize=5000,maximumsize=10000
Simply customize "5000" and "10000" to the desired sizes for your server.
