# 0x803F7001: Windows could not find a digital license

0x803F7001 means Windows could not find a valid digital license for this device. A motherboard change, skipping the key during setup, or a system upgraded from Windows 7/8 that was never activated are the most common scenarios. Entering the product key or recovering the account-linked license with the troubleshooter resolves it.

## Most common causes

- The motherboard was replaced and the digital license does not recognise the device
- The key was skipped during a clean install and the device never had a digital license
- The license was not linked to a Microsoft account
- The activation server is temporarily unreachable

## Step-by-step fix

1. Enter your 25-character key under Settings → System → Activation → "Change product key".
2. If the device was activated before, sign in with your Microsoft account and follow Activation → "Troubleshoot" → "I changed hardware on this device recently".
3. Check the internet connection and date/time; turn off any VPN.
4. Activate manually with "slmgr /ipk KEY" and "slmgr /ato" in an elevated Command Prompt.
5. If that fails, use phone activation via Windows + R → "slui 4" or send the error code to your seller.

## Frequently Asked Questions

### I got Windows through the free upgrade and have no key. What now?

The free upgrade created a digital license tied to the device; if the motherboard is unchanged, the troubleshooter restores it. If the motherboard changed and the license was not linked to an account, a new key is required.

### Are 0x803F7001 and 0xC004F213 the same?

They are two faces of the same situation: no license/key found on the device. The fix steps are identical; entering the key is the quickest route.
