Microsoft has released what it calls the final security patch for Windows 10, addressing a significant number of vulnerabilities. The October update resolves 172 security holes, highlighting the importance of extended updates for users. This comes as support for the operating system officially ends.
The latest update for Windows 10, released in October 2025, serves as the operating system's final major security patch. According to TechRadar, this patch tackles a 'bewildering number' of security flaws, specifically resolving some 172 security holes. The update underscores the value of extended updates, which Microsoft offers for a fee to provide ongoing security fixes beyond the standard support lifecycle.
Windows 10's mainstream support ended in 2020, with extended support set to conclude on October 14, 2025. This final patch arrives just before that deadline, ensuring users receive critical protections against known threats. TechRadar's coverage emphasizes how the sheer volume of fixes—172 in total—demonstrates the ongoing risks for those not opting into paid extended security updates (ESU).
For users still on Windows 10, Microsoft recommends upgrading to Windows 11 where possible or enrolling in ESU to maintain security. The patch is available through standard Windows Update channels, focusing solely on vulnerability remediation without adding new features.
