This is a tiny cheat sheet for basic administration of local users on a Windows Server 2016 machine using PowerShell:
Listing local users and their parameters
Get-LocalUser | Format-List
Listing available properties to modify
Get-Help Set-LocalUser
Setting a parameter for a local user
Set-LocalUser somenamehere -Password somepassword
When setting boolean parameters, remember to use $false and $true, rather than false and true. Otherwise you will get an error due to passing a string instead of a boolean.
