Microsoft Fixes a Critical Security Flaw in Windows 10

Last week, Microsoft warned Windows 10 users about a critical security flaw involving the Windows Print Spooler service. Known as the PrintNightmare, this security flaw could allow hackers to remotely execute code with system-level privileges.

Hackers can use this exploit to install programs, modify data, and create new accounts with full admin rights.

The vulnerability was revealed when security researchers accidentally published a proof-of-concept (POC) exploit code. It was deleted immediately afterward, but not before it was taken from GitHub, putting millions of computers at risk.

Microsoft has finally started rolling out an emergency Windows patch to address this critical flaw. Microsoft has issued this out-of-band security update to several versions of Windows 10, Windows 8, and 8.1. Surprisingly, the software maker has even issued the update to Windows 7, which officially went out of support last year.

Microsoft has still not issued the update to a few versions of Windows, but the company says that “security updates for these versions of Windows will be released soon.”

Microsoft has warned that these updates should be installed immediately since it is a critical security flaw.

We recommend that you install these updates immediately. The security updates released on and after July 6, 2021 contain protections for CVE-2021-1675 and the additional remote code execution exploit in the Windows Print Spooler service known as ‘PrintNightmare’, documented in CVE-2021-34527.
