Microsoft says the emergency security updates released at the start of the week correctly patch the PrintNightmare Print Spooler vulnerability for all supported Windows versions and urges users to start applying the updates as soon as possible.

This clarified guidance comes after security researchers tagged the patches as incomplete after finding that the OOB security updates could be bypassed in specific scenarios.
