Keep getting activation error in Event Viewer

The error code 0xC004F074 indicates that the Software Licensing Service failed to connect to the Key Management Service (KMS) to activate the software. This can happen even if your Windows and Office applications appear to be activated because the activation process may not have completed successfully in the background.

Here are a few steps you can take to troubleshoot this issue:

1. Check KMS Connectivity: Ensure that your system can connect to the KMS server. This may involve checking network settings or firewall rules that could be blocking access.
2. Run Activation Commands: You can manually attempt to activate Office using the command line. Open Command Prompt as an administrator and run:
   • cd \Program Files\Microsoft Office\Office16 (adjust the path if necessary)
   • cscript ospp.vbs /act
3. Restart the Software Licensing Service: Sometimes, simply restarting the service can resolve the issue. You can do this by running the following commands in an elevated Command Prompt:
   • net stop sppsvc
   • net start sppsvc
4. Check Event Viewer for More Details: Look for additional error messages in the Event Viewer that might provide more context on the activation failure.

If the problem persists, consider reaching out to Microsoft support for further assistance, as they can provide more specific guidance based on your licensing situation.

Hi,

This error cannot occur on a licensed home computer, so please ask your company's system administrator for clarification.

For home computer this error code says the activation and possibly installation were made illegally. This could do unfair seller, technician or any other person during computer repairing. Please, ask PC manufacturer whether it preinstalled Windows on this device. And if you don't have a license you need to buy one.

How did you purchase your Windows and what was the price?

I suppose you may ignore these events if you do not see any real problem. However, please check the result of slmgr /dlv command.
