We couldn’t upgrade your edition
Try upgrading your edition of Windows again or contact your your system administrator or Microsoft. Error code: 0x0
When you arrive on this post, you might have been frustrated with above error message when upgrading Windows 10 Home edition to Pro edition. Without too much talking, here is the solution:
UNINSTALL YOUR ANTIVIRUS PROGRAM
Yes, it’s. Whatever your antivirus program, uninstall it first before entering Pro edition key for the upgrade.
In my case, my Asus ROG GL502VT came with McAfee LiveSafe. It had successfully destroyed my day until I realized that it’s the cause of the issue.
You can reinstall your Antivirus program again after the edition upgrade completed successfully.
