Change Storage Location of Smart Paging File and Snapshot location for HyperV VMs

So when you provision a big HyperV machine and forget to change the default location for "Virtual Machines" it won't take long till the system volume of your Hyper visor starts to run out of disk.

After you punish the admin that didn't change the default Virtual Machine Location you can use this script to move the paths to same folder as the first VHD of each VM.

$vms = get-vm -ComputerName SOMEHYPERVBOX | where {$_.smartpagingfilepath -like "c:\*"} | select Name, SmartPagingfilepath foreach ($vm in $vms) {     [string]$newpath = [system.io.path]::getdirectoryname((Get-VM -ComputerName SOMEHYPERVBOX -Name $vm.name | Get-VMHardDiskDrive|select -first 1).path)     [string]$name = $vm.name     Move-VMStorage -ComputerName SOMEHYPERVBOX -VMName $name -SmartPagingFilePath "$newpath" -SnapshotFilePath "$newpath" }

This works for us, you may need to tweak it to comply with the particular requirements of your environment.

Good luck and make sure that Admin never rolls servers into prod with default settings again!
