Similar to other error codes, this error code doesn’t just appear for Windows 11 users. It is a pretty common error for Windows 10 OS users as well.

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 which 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.
