How to activate Windows 8

Yes, you have to activate your copy of Windows. Only certain developer versions of Windows 8 are pre-activated for a certain time

Quick Links:

Activating Regular Copy

6. Now at the bottom click on View Details in Windows Activation

7. If Windows 8 is not activated you will be able to activate Windows 8 there or see the last numbers of your current product key

Keep in mind, you can’t activate Windows 8 on a virtual machine without internet connection.

If you are installing Windows 8 on a real PC, the chances are good that Windows 8 will automatically ask you to activate Windows 8. Let us know if you run into any activation errors. I had some trouble with the slui.exe in Windows 7, so it’s possible the error is still there and the slui.exe is still causing problems in some cases, we’ll see.

Problem: Activations Fails

A popular reason why the activation fails is that you used the key to activate too many machines. Usually a key is only valid for one machine, unless you have a special volume licensing key that allows activation via MAK or KMS

Problem: Error Code 0xC004F061 When Activating Windows 8

If you see error 0xC004F061 when activating your copy, you have a wrong key. The error means that you did not have any other Windows versions on your system and you are not entitled to use an upgrade key – if you are 100% sure you have upgraded from a previous version, contact Microsoft’s support page

Volume Licensing: Activating Windows 8 Pro and Windows 8 Enterprise (KMS/MAK)

Obviously, activating the Enterprise version is a little different if you want to activate multiple machines

  • Windows 8 Pro Supports: KMS server/ Active Directory Based activation
  • Windows 8 Enterprise Supports: KMS / ADBA / MAK

Technet Subscribers may need a volume license key to activate certain ISO files that can be downloaded from the Technet website. Only the regular Windows 8 ISO can be activated with a regular or Pro key.
