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 a 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.
