Have you upgraded to Windows 10 and not able to explore all features because of activation errors? There are some common activation errors that can show up on your newly installed Windows 10. Learn what this activation error means, common Windows 10 activation errors and how to fix them below.
If you upgrade to Windows 10, the new OS will take the product key and activation details from your earlier OS. These are then saved on Microsoft servers, along with your PC details. If you clean install Windows the first time, you may face activation problems. If you performed an upgrade the first time, activated Windows 10, and then clean installed Windows 10 on the same PC, then there will be no activation issues as the OS will pull activation details from Microsoft servers.
