Hi. I'm David, and I'm happy to help you.
If your device is eligible, the Enroll Now option should appear under "Settings > Update & Security > Windows Update". Once you select the Enroll Now option, the on-screen instructions will appear. Just follow them carefully. It's really not complicated.
If you don't see it yet, don't worry. Microsoft is rolling out the ESU enrollment wizard gradually. As long as your device is running Windows 10 version 22H2 and has the KB5065429 update installed (released on September 9, 2025), the option should become available soon.
According to reliable sources, Microsoft has confirmed that all eligible users will receive access before the official end of support for Windows 10 on October 14, 2025.
I also have a Windows 10 device and haven't received the option yet, so you're definitely not alone.
Feel free to ask back any questions.
