It’s now 2026. After the false dusk of 2025, when Microsoft nearly killed Windows 10 but then relented by offering free security updates for all users, we have the next deadline. This time, we’re told, Windows 10 really will come to an end in October, 2026.
Meantime, the analyst data does not make pretty reading. It seems Windows 11 is still failing to win over the Windows 10 crowd. In fact, it’s even worse than that. While its accuracy will prompt debate, StatCounter says Windows 10’s market share has grown from 42% in October to 46% now. Windows 11 can’t get much beyond the 50% mark.
Microsoft confirms “you can enroll in ESU any time until the program ends on 13 October, 2026, however devices will be more vulnerable and susceptible to viruses and malware before enrollment. If you enroll after the ESU program launches, you will receive any previous updates as well as any future updates.”
You can pay for the Windows 10 Extended Security Updates (ESU) if you so choose, either with cash or Reward points. But it’s free if you have a Microsoft account and you agree to sync your PC settings using Microsoft’s OneDrive.
This month’s Patch Tuesday includes the first Windows 10 ESU update of 2026. Per PC World, “Windows 10 users should install update KB5073724 immediately, which fixes several security vulnerabilities in the operating system.”
Even more critically, per Windows Latest, “the January 2026 update for Windows 10 includes new Secure Boot certificates, as the older certificates had recently expired.” This is not optional. “If they are not replaced, Secure Boot may stop trusting new boot components, and this makes your PC vulnerable.”
Beyond that, “this month’s update for Windows patches at least 112 security issues, including 57 Elevation of Privilege vulnerabilities, 22 Information Disclosure vulnerabilities, and 5 Spoofing vulnerabilities.”
