What is the history of your Windows installations?  Windows 7 to Windows 8.1, Windows 8.1 to Windows 10?


Did you have a legal product key for any of these installations?


Where these installations made using the installation media for the original version of Windows installed.


Did you upgrade from Windows 8.1 to Windows 10 or did you use the media creation tool to create a ISO file and use that to create the installation media to install Windows 10?


If you upgraded from a legal copy of Windows 8.1 (which was activated) to Windows 10, the product code was digitally recorded. 

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

The key posted above...has many hits as a key which was posted by various websites as pertaining to the trial download/installation of Windows 10 during a the free-upgrade/try-it-now period of time.  That period ended on the last day of July 2016.


You can Google the listed key and see for yourself that the websites posting such...tend to be both legitimate and less-than-legitimate websites reflecting dated data/information.


Excerpt from PC World Article:  "Officially, the free upgrade period for Windows 10 expires at 11:59 p.m. (UTC-10) on July 29, 2016. For Americans who never think beyond Pacific, Eastern, Mountain or Central time, that means that you have just bit more time beyond midnight to complete the upgrade—unless you live in Hawaii.


One catch if you’re a procrastinator: according to Microsoft, all upgrades must be fully completed by the deadline—you apparently won’t be able to wait until the last minute. As part of my update of how to install Windows 10, I found that I needed a solid two hours (maybe more, maybe less) to upgrade an older PC. We don’t know what exactly will happen if you’re in the middle of the upgrade when it expires, but it’s probably best not to find out."


Bottom line:  You are trying to activate with an illegal key,


BC Forum Rules prohibit any member from providing you with assistance regarding installation of Windows via illegal means.


Excerpt:  "No subject matter will be allowed whose purpose is to defeat existing copyright or security measures. If a user persists and/or the activity is obviously illegal the staff reserves the right to remove such content and/or ban the user. This would also mean encouraging the use or continued use of pirated software is not permitted, and subject to the same consequences."


This topic is now closed.  If you have any questions about my actions...please convey such to me via PM and I will attempt to clarify/respond intelligently.
