Windows activation problem after upgrading from windows 10 to windows 11

Question

My computer now reports that windows is not activated after upgrading from windows 10 to 11. Error messages says that it cant connect to my organization's activation server. I am not aware that I am part of any organization. error code 0xC004F074. What can I do about this?

Answer 1

The error code 0xC004F074 indicates that the Key Management Service (KMS) is unavailable, which can happen for several reasons, especially after an upgrade. Here are some steps you can take to resolve this issue:

1. Check the KMS Host: Ensure that your computer is trying to connect to the correct KMS host. If you are not part of an organization, your computer may be trying to connect to a KMS server that is not available.
2. Network Issues: Make sure that there are no networking issues preventing your computer from reaching the KMS host. Check if TCP port 1688 is open between your computer and the KMS server. You can use the Test-NetConnection PowerShell cmdlet to verify this.
3. Service Status: If you have access to a KMS host, check if the Software Protection Platform Service (sppsvc) is running on that server. If it has stopped, you will need to start it.
4. DNS Records: Verify that the KMS DNS records are correct. You can check the _VLMCS SRV record in the DNS management console to ensure it points to the correct KMS host.
5. System Time: Ensure that the system time on your computer is synchronized with the KMS host. Time discrepancies can cause activation issues.

If you are still unable to activate Windows after trying these steps, you may want to consider using the Microsoft Support and Recovery Assistant (SaRA) tool, which can help troubleshoot activation issues.

Answer 2

Hi,

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.
