Microsoft has officially ended support for Windows 10, but users can receive critical security updates until October 12, 2027, through the Extended Security Updates (ESU) program at no cost. To qualify, users must have a Windows 10 PC running version 22H2 or later and sign in with a Microsoft account, excluding Enterprise and Education editions. In the European Economic Area, customers automatically qualify for free ESU subscriptions without needing a Microsoft account. Enrollment can be done through Settings > Windows Update, and users may need to back up their settings or redeem Microsoft Rewards points. Business customers must purchase ESU subscriptions at a higher cost. Users should be cautious of potential issues, such as cloud storage consumption during backup.
