Troubleshooting Tips
- Invalid Product Key:
If you find yourself staring at error 0xC004F050, it may be due to an invalid product key. Double-check the key’s accuracy. Also, make sure the product key corresponds to the specific Windows 10 edition, such as Home or Professional.
- Product Key Already in Use:
A single product key is designed for one active Windows installation. If we have used a Microsoft account in an old Windows version, activate it online before using it for a fresh Windows installation.
For local user accounts, deactivate the product key by running the following command as an administrator:
slmgr /upk - Windows Activation Servers Busy:
Error code 0xC004F050 might occur due to server congestion. In such cases, wait for a while and try to activate it again later when the servers are less busy.
- Major Hardware Changes:
Major hardware changes, like a motherboard replacement, can trigger the need for Windows reactivation. Unlike earlier Windows versions, Windows 10 lets us link our license to our Microsoft account.
We can check our license status in “Update & Security” under “Activation” in the Settings app. If linked, follow these steps for a smooth reactivation:
- First, log in with the Microsoft account.
- Then, go to “Activation” under “Update & Security” and click “Troubleshoot.”
- Next, choose “I changed hardware on this device recently” and select the current device.
- After that, click “This is the device I’m using now” to automatically transfer and reactivate the Windows license.
For local user accounts, a complete reactivation is necessary after hardware changes.
- Activating Windows 10 by Phone:
When online activation fails, we can still activate it via phone as seen here:
- Right-click the Windows logo and select Command Prompt or Windows PowerShell.
- Then, enter `slui 4` in the command line and press Enter.
- Now, get the available phone numbers for our country.
- Next, enter the installation ID displayed on the screen into the phone’s keypad when prompted.
- Enter the confirmation ID received by phone on the Windows device to activate Windows 10.
