    thanks in advance.
    Many people are upgrading windows 7, 8, 8.1 pro to windows 10, But I’m still have some conclusion, as I heard about its technical issue during upgrading and after up-gradation.
    I just activated my OS being purchased a product key from ODosta Store, Now I want to upgrade, So please clear my doubt about it asap.

    • If you have already activated Windows, there is nothing else to do. Just enter your key during installation/upgrade process and Windows will automatically activate after installation, if there is working internet connection available.
