Hi Debbie Heslop,
You can still sign up for Windows 10 Extended Security Updates (ESU) even after the deadline. Enrollment is open until the program ends on October 13, 2026, so as long as your PC is running Windows 10 version 22H2 with the latest cumulative updates, you are eligible. You’ll need to purchase an ESU license (consumer or commercial, depending on your use case) and activate it with the product key on your device.
If you find this information useful, please accept answer so that it could be spread to more people in need. Thank you :)
