#Requires -RunAsAdministrator #Requires -Version 5 <# .Synopsis Activates Windows via KMS .DESCRIPTION A drop in replacement for slmgr script .INPUTS string[]. You can pass the computer names .OUTPUTS None if successful. Error message if there is an error. .EXAMPLE Start-WindowsActivation -Verbose # Activates the local computer .EXAMPLE Start-WindowsActivation -Computer WS01 -Credentials (Get-Credential) # Activates the computer named WS01 using different credentials .EXAMPLE Start-WindowsActivation -Computer WS01, WS02 -CacheDisabled $false # Disabled the KMS cache for the computers named WS01 and WS02. Cache is enabled by default. .EXAMPLE Start-WindowsActivation -Computer WS01 -KMSServerFQDN server.domain.net -KMSServerPort 2500 # Activates the computer named WS01 against server.domain.net:2500 .EXAMPLE Start-WindowsActivation -ReArm # ReArm the trial period. ReArming already licensed devices can break current license issues.
