What happened on your PC before Windows was no longer activated.

Where did you get your Windows licence was that pre-installed on the PC or did you purchase a full retail Windows licence from Microsoft or from a 3rd party retailer, and if so, do you have the product key?

Or is your Windows licence based on a previous Windows 7 or 8 licence?

Click your Start Button, type cmd then right click Command Prompt and choose 'Run as Administrator'

Run or paste this command and hit Enter:

slmgr.vbs /dlv

Please post a screenshot of the resulting dialog

Follow these steps in order on the Windows 10 device:

1. Confirm Windows 10 version
   • Press Windows key + R, type winver, press Enter.
   • Ensure the device is running Windows 10 version 1607 or later. If not, update Windows first using the steps in update Windows 10.
2. Run the Activation troubleshooter from Settings
   • Select Start > Settings > Update & Security > Activation.
   • Select Troubleshoot.
   • Wait for it to complete and see if it activates Windows or changes the error code.
   • If the error code changes, use the new code and match it against the list in Get help with Windows activation errors and follow the specific steps.
3. If the error is 0x803F7001 or “no valid license found”
   • This means Windows cannot find a valid license for the device.
   • If there is a valid product key:
     1. Go to Start > Settings > Update & Security > Activation.
     2. Select Change product key and enter the 25‑character key.
   • If there is no product key, select Go to Microsoft Store on the Activation page and follow the prompts to purchase a digital license.
4. If the error is 0x800704CF or similar “no valid license” errors
   • Use a valid product key as above (Activation page > Change product key).
   • If major hardware changes were made (for example, motherboard replacement), run the Activation troubleshooter again from the Activation page and follow the reactivation path after hardware change.
5. If the error is 0xC004F211 or 0xC004F213 after hardware change
   • These indicate hardware has changed or no product key was found.
   • On Start > Settings > Update & Security > Activation:
     • If a product key was previously used on this device, select Change product key and enter it.
     • Or select Go to Microsoft Store to purchase a new license.
   • If the license was linked to a Microsoft account before the hardware change, sign in with that same Microsoft account, then on the Activation page select Troubleshoot and use the “reactivate after a hardware change” path.
6. If the troubleshooter repeatedly fails with “unexpected issue” and no specific code
   • Ensure the device is online and time/date are correct.
   • Retry later in case of temporary activation server issues.
   • If repeated attempts still fail and no listed error code appears, contact Microsoft customer support directly so they can check the license and, if applicable, reactivate it.

If the PC is pre‑owned or repaired and activation still fails after these steps, the existing key may already be used beyond its limit or may be invalid. In that case, a new product key or copy of Windows is required.
