Due to the severity of the issue, Microsoft issued an out-of-band update for several versions of Windows, including Windows 10, Windows 8.1, and even Windows 7. In addition to people reportedly finding ways around the patch, the fix also stops some printers from working.

The company also explained that an updated patch that should address the issue is on the way in the next couple of days.
The PrintNightmare saga continues to evolve. While people report ways around the patch for the vulnerability, Microsoft claims that the patch works as intended, and is only ineffective when people change default registry settings.
