    I bought Parallels Desktop For Mac Business Edition in July 2021 and since then I'm having troubles with Windows 10.
    I see 'Activate Windows' on the bottom right corner of my desktop.
    I entered my Windows product key as provided by my institution, I get the a message saying 'The product key you entered didn't work. Check the product key and try again, or enter a different one. (0x800f0805).'
    I searched all the relevant articles from Windows, downloaded ISO files and still cannot fix this problem.

    Your help is much appreciated
