It can be because of a mismatch between the KMS client and the KMS host server. So, for this error to vanish, the KMS client needs to be updated to match the KMS host server version.

Moreover, Windows 11 activation error 0xc004f074 could also appear for multiple other reasons. Some of these are mentioned below:

• Because of a time difference between the KMS client and KMS host machine.
• It can occur after the installation of a cumulative update.
• Not using a genuine serial key to activate Windows 11.
• The product key is already used in another copy of Windows 11.
• Corrupt Windows 11 system files.
• It could be because the Windows Firewall or Windows Defender is interfering with the activation process.

1. Use the Software Licensing Management Tool

2. Search for Command Prompt and run it as an administrator.

4. Execute the below command to uninstall the existing product key.slmgr.vbs /upk
5. Type the below command to re-install product key and press Enter.slmgr.vbs /ipk <New_product_key>

In the last command, you need to replace the <New_product_key> with the actual product key of your Windows 11 copy.

Once the command executes, reboot your PC and see if this fixes the issue or not.

Hold on… it says Windows Pro version? Did you laptop ship with Pro or Home (in all probability, it would Home edition). You have possibly installed the wrong version of Windows. Unless you purchased a genuine Pro key, your activation won't work. Remove windows and install the Home version shipped with your laptop.
