Microsoft announced that the world's most popular PC operating system, Windows 10, will attain EOS (end of support) on October 14, 2025. From that date forward, the company will no longer release regular security updates for the OS, or the so-called "patch-Tuesday" updates for Windows 10. This announcement only covers the client Windows 10 editions, and not Windows 10 Enterprise LTSC (long-term servicing channel), or special editions of Windows 10 for large organizations and government agencies. Organizations on the client editions, such as Windows 10 Pro, can avail the ESU (extended security update) program, which will give them access to critical security updates, but no new OS or software features. Microsoft took the opportunity to urge those on Windows 10 to upgrade to the latest Windows 11 operating system. The company plans to launch its next-generation Windows 12 some time in 2024.
