* 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?
