Microsoft has quietly extended its Windows 10 Extended Security Updates (ESU) program to run through October 12, 2027, a full year beyond its original end date of October 12, 2026 [1, 2, 3]. The ESU program offers security-only updates and applies to users who were already enrolled before, who will now have automatic coverage without any additional payments or action required [1, 3].
Windows 10 officially reached its end of support in October 2025, ending all mainstream updates and fixes except those in the ESU program [1, 2, 3]. Despite the official end, Windows 10 remains widely used; recent data shows 24% of Steam users are still on 64-bit Windows 10 [3]. Slower adoption of Windows 11—due partly to its higher hardware requirements—has led many users and organizations to stay on Windows 10 [2, 3].
The ESU program does not include feature upgrades, only security patches, helping to reduce risks from vulnerable and outdated systems [1, 3]. Ars Technica noted, "If you are still clinging to Windows 10, you don’t have to do anything but enjoy that extra year," describing the extension announced earlier this year in June 2026 [2].
Microsoft’s extension aims to lessen security threats from the large installed base of Windows 10 PCs by providing continued protection for another year [1, 2, 3]. The next concrete milestone will come on October 12, 2027, when the Extended Security Updates program for Windows 10 will conclude [1, 2, 3].
