Powershell: Change UPN on list of users

I needed a script to bulk change a list of users to a new UPN i came up with this.

#
$Users = gc c:\temp\users.txt | get-ADUser

foreach ($User in $Users)
$UserUPN = $User.UserPrincipalname
$UserUPNwithOutDomain = ([regex]::matches($UserUPN, "([^@]+)")).value[0]
Set-ADUser $User -userprincipalname "$UserUPNwithOutDomain@microsoft.com"
}

Vmware: Powershell List all Datastores and virtual machines within

Purpose: Need to know if i had any empty datastores attached to my ESXi hosts. Came up with this one liner which will list out all datastores and the vms that are within empty or not.

get-datastore | select name, @{name="VM";e={get-datastore $_.name | get-vm } } | fl

VMware: Powershell Query each ESX Hosts Syslog
