You can easily extend the life of Windows 10 even after October 14, 2025. No matter what date you do it, it will remain valid until October 13, 2026. It's likely that you'll be able to extend your Windows 10 life for free and easily until October 13, 2027, a year from now (September 2026). We look forward to resuming the service in a year.
