Hello and welcome to Microsoft Community!
I understand that you are experiencing 0xc004f074 when activating your product key, and I think I need to know the source of your product key, which will allow me to better help you troubleshoot the problem.
In general, this error code may indicate:
0xC004F074 and its description "Key Management Server (KMS) not available"
Error: 0xC004F074 Software License Service reported unable to activate the product. No Key Management Service (KMS) could be contacted.
It is also possible that the system files are corrupt.
Next I will provide my method to help you try to fix the error.
Using the slmgr.vbs command
1. Press Windows Key + S, type cmd, and then select "Run as administrator" at the command prompt.
2. Type the following command (replace the X in the code with your 25-digit product key number) and click Enter
slmgr.vbs -ipk XXXXX - XXXXX -XXXXX -XXXXX -XXXXX
3. Type the following command and click Enter
slmg.vbs -ato
4. Restart your computer and see if your device shows the same error.
To run an SFC scan
1. Open a command prompt with administrative privileges.
2. Type the following command and hit Enter
sfc/scannow
3. Wait for the command to finish running and then restart your computer, which may replace and fix the error code 0xc004f074 System files without a product key but with a digital license that may cause failure to activate Windows.
Run Update and Activation Troubleshooting
1. Press Windows Key + I to open the Settings application, and then select Update and Security.
2. Click Troubleshooting in the left pane and select Other Troubleshooting.
3. Now, select Windows Update and click the Run Troubleshooting button.
4. If this does not solve the problem, go back to the Update and Security window and select Activate in the left pane.
5. Finally, click on the Troubleshooting option and apply any recommendations from the tool.
On the other hand, Windows Activation Troubleshooting is the best option for most activation issues.
