How to Fix Windows 8 RTM Activation Issue?

After installing Windows 8 RTM, I was facing an issue that says "Windows can't activate right now. Try activating Windows later". I tried it multiple times but couldn't figure out what was the actual issue here.

Later @LBugnion shared me the trick to resolve this issue which I am going to share here in my blog, so that you can find it useful.

After installing Windows 8 RTM, you may probably face an issue while activating your Windows OS which will say the following:
Windows can't activate right now. Try activating Windows later. If this issue persists, contact your system administrator or technical support department for assistance.

If you are one of them, no need to worry. Just follow the below mentioned steps:
    • Open "Command Prompt" under Administrative Privileges.
    • Enter the following in the Console Window: slmgr.vbs -ipk [PRODUCT_KEY] and then hit enter. Replace "[PRODUCT_KEY]" with your genuine Windows 8 Product Key that you received.

Once you are done with the above mentioned steps, your Windows 8 will activate with the license key. Make sure that, you are connected to the internet before activating Windows.

  1. Alternative : enter 'SLUI 3' in a command prompt.
    This will open the GUI to change your activation key.

  2. Command prompt worked perfect but still same error.

  3. Check out whether you have entered valid Product Key. Also try out from the GUI by visiting this page:

    Control Panel\System and Security\Action Center\Windows Activation

    Let me know.

  4. slmgr.vbs -ipk [PRODUCT_KEY] did not work for me with a valid code but SLUI 3 worked like a charm with the same code.


  5. where I can get the activation key?

  6. Once you purchase Windows 8, you will get the key.
