PrintNightmare Mitigations

Make sure your computer has the proper mitigations against PrintNightmare by using this PowerShell module. If you have the correct updates installed, you will need to add or edit registry settings for full protection. This module will help.

How to install this

Most users should grab it from PowerShell Gallery:

Install-Module PrintNightmareMitigations

You may also download and install this manually.

How to run this

Run Set-PrintNightmareMitigations to patch this computer. Changes do not require a reboot. The optional parameter, -RestrictDriverInstallationToAdministrators, provides optional extra protection.

Set-PrintNightmareMitigations [-RestrictDriverInstallationToAdministrators]

To see if this computer has been patched, run:

Test-PrintNightmareMitigations

Use Group Policy if possible

While this module can test if the correct GPO's are being applied, you should use Group Policy in a domain environment. That will make your life easier. This module is better suited for standalone or workgroup computers. 0
