Firstly, download the RSAT tools for Windows 7 or Windows 8 of the appropriate bittiness.

Then install them using: wusa <RSAT Installer Filename>.msu /quiet

You can then enable the Powershell AD cmdlets (or indeed any other RSAT components) from the command line using dism.exe thus (careful, the featurenames are case-sensitive):

dism /online /enable-feature /featurename:RemoteServerAdministrationTools /featurename:RemoteServerAdministrationTools-Roles /featurename:RemoteServerAdministrationTools-Roles-AD /featurename:RemoteServerAdministrationTools-Roles-AD-Powershell

For some reason it won’t install “dependent” parent components unless you explicitly tell it to install them, which is a pain but workaroundable.

If you need to change the drivers for a large number of printers, such as on a print server, then you can use the following Powershell to do it. Set $driver to the name of the driver you wish to set and $pattern to match for the printers you wish to affect (so you don’t change the driver on printers you don’t want to).

Note: This script will run pretty quickly, but depending on the number of printers it may take upwards of 10 minutes for Windows to do all the background processing associated with the driver changes. Keep an eye out for a bunch of rundll32.exe processes which will spawn; once they close themselves down the changes should be complete.

$driver = "HP Universal Printing PCL 6 (v5.4)"
$pattern = "HP"
$printers = gwmi win32_printer
foreach($printer in $printers){
        $name = $
        if($name -match $pattern){
                & rundll32 printui.dll PrintUIEntry /Xs /n $name DriverName $driver
