    Bad COA code on new device


    I'll just put it this way.

    I had purchased a Microsoft Windows 10 Pro disk (and it comes with a COA code)

    And it worked fine.

    The first device is Dell Systems XPS L321X.

    The second device is Fujitsu UH 554.

    After the first installation, the code becomes strapped with my account.

    Now I am replacing my Dell Systems XPS L321X with a new device, so I decided to go for "change in hardware" but that didn't work.

    More importantly, Microsoft refuse to recognize my CoA. Why is that?

    :)

    new Windows 10 coa sticker damaged; can't read the COA code

    Hi!

    I'm having trouble reading my COA code from a brand new copy of win 10. I guess i damaged the code when scraping of the protective layer that was covering the code.

    What can i do?
