Thank you for reaching out to Microsoft Q&A forum. I know it’s frustrating to see Windows asking for activation after a reset.
The first thing to check is whether the correct edition of Windows is installed. Surface devices can only activate the same Windows edition they originally shipped with (for example, Windows 11 Home vs. Windows 11 Pro). After a reset, Windows may sometimes install a different edition, which will prevent activation.
You can verify this by going to Settings > System > About, then checking the Edition listed under Windows specifications. If the installed edition doesn’t match what originally came with the device, activation won’t complete until the correct edition is installed.
Once you’ve confirmed the edition is correct, the next thing to check is whether the original OEM license is still being detected by the device. On Surface laptops, the Windows license is normally stored directly in the system firmware, so it shouldn't be lost during a factory reset.
To verify this, open Command Prompt as Administrator and run the following command:
wmic path SoftwareLicensingService get OA3xOriginalProductKey
If a 25‑character product key appears, that confirms the original Windows license is still embedded in the Surface hardware. In most cases, Windows will automatically use this key to activate once it successfully connects to Microsoft’s activation servers.
If the correct Windows edition is installed and the OEM key is present, but Windows still shows as Not activated, I highly recommend contacting the Microsoft Support team so they can manually validate and restore activation on the backend.
I hope this helps get things moving. Please don’t hesitate to reach out if you have any additional questions.
