Microsoft has released Windows 10 cumulative updates for the month of August 2021. These mandatory security updates are available for the latest Windows 10 version 21H1 along with other supported versions of the operating system.

The company has addressed several critical security vulnerabilities in Windows 10 with today's Patch Tuesday update. "The spectre of the PrintNightmare continues to haunt this patch Tuesday with three more print spooler vulnerabilities, CVE-2021-36947, CVE-2021-36936 and CVE-2021-34481," Immersive Labs’ Kevin Breen, Director of Cyber Threat Research, writes. "All three are listed as Remote Code Execution over the network, requiring a low level of access, similar to PrintNightmare."
