October 14, 2025, marks the end of support and security updates for the Home and Pro versions of Windows 10. That means it’s also the end of official guaranteed feature and security updates for Windows PCs that don’t meet Windows 11’s hardware requirements.
Viewed from early 2022, that date is still comfortably far off. Many Windows 10 PCs will break over the next three and a half years, and plenty of people who want to upgrade to nicer or faster hardware will have opportunities to do so. But those who enjoy repairing, maintaining, and upgrading older hardware to keep it useful will be peering over the edge of that Windows 10 update cliff before they know it.
So what happens to that hardware when Windows 10 goes away? Running Windows 11 on unsupported hardware is one possible solution, but we have no idea how long Microsoft will allow users to install, run, and update Windows 11 on older PCs. The company could cut off these computers’ security updates tomorrow, or it could allow them to run the new OS indefinitely. That uncertainty is hard to plan around.
