Microsoft will stop providing security updates for Windows 10 on October 14, 2025. The final monthly security update will be released on that date, coinciding with the end of support for Windows 10, version 22H2. Users will no longer receive security patches, bug fixes, or feature updates after this date. Approximately 42.99% of all PCs currently run Windows 10, which translates to millions of unsupported devices. Users have several options: upgrade to Windows 11 for free if their device meets the requirements, purchase a new PC with Windows 11, pay for an Extended Security Update (ESU) subscription for additional security updates, utilize OneDrive for free additional security updates, or switch to a different operating system like Linux or ChromeOS.
