Windows 10 will reach its "end of life" on October 14, meaning it will stop receiving security updates. This leaves users with three main choices to ensure their computers remain secure. They can upgrade to Windows 11 if their hardware is compatible, purchase a new PC with Windows 11, or enroll in Extended Security Updates (ESU) for an additional year of support. The article focuses on the ESU option, which can now be accessed for free in many cases. To enroll, users must first ensure their PC is fully updated and that they are using an administrator account. They should then check their eligibility for a free Windows 11 upgrade. If not eligible or choosing not to upgrade, users can proceed to enroll in ESU through their Settings menu. For US users, the free ESU enrollment involves a year-long extension but requires linking their Windows login to Microsoft's cloud services like OneDrive. There are also limitations on the free OneDrive storage, with users needing to manage what they back up. Completing these steps will provide an additional twelve months of security updates for Windows 10.
