Windows 8.1 Activation issue error code 0xC004E028

* Original Title: For activation, what does this error code 0xC004E028 mean? Thanks


Recently I used the DVD I bought from Microsoft to do a clean win8.1 install on one of my laptop which has oem win8.1 previously. After login I found in the event viewer there is an error:license activation (slui.exe) failed with the following error code: hr=0xC004E028。

Please help me, what does this mean? I tried to search online and found nothing useful. Will this error code be a matter?

Thank you!

Hi Arthurz,
1. What is the complete error message that you get when you try to activate Windows.
2. What is the Make and Model of the computer? 
I would first suggest you to try to phone activation and check if you are able to activate Windows.

Click on to the below links and check if it helps:
Further, you may contact a Microsoft Product Activation Center by telephone to activate manually:
Hope this information helps, please reply with the status of the issue for further assistance.
