In 2021, for example, a security vulnerability in the printer spooler was found that allowed attackers to gain system rights. System rights are one level above administrator rights and allow the installation of arbitrary applications and almost unlimited changes to Windows settings.
As new patches had to be developed for several months to close the gap, it was finally given the name "Print Nightmare".
In Windows 11 24H2, Microsoft has now integrated the Windows Protected Print mode, or WPP for short, which was announced some time ago. It replaces the manufacturer's drivers on many printers and at the same time prevents the installation of new printer drivers.
This is intended to prevent malicious code from entering the computer via the drivers. It also ensures that the common tasks of the printer spooler are no longer executed with system rights, but only with user rights. In this way, Microsoft is closing the security gap that led to the Print Nightmare.
