WZor: Win10 Preview 10147 cannot be activated with Win8.1 key

On June 19th, when we installed some Win10 previews, we would ask for the "Activate" situation, such as installing Build 10147. After this installation, friends will find it is inactive and need to enter the product key. When we tried to use the preview key provided by Microsoft, we found that it had expired.

But some friends are more flexible, think of using their own Win8.1 legal key to activate, because it is basically effective before. But this time, this road was also blocked by Microsoft. Russia broke the news that WZor tried to use this method to get 10147, and found that it could not be used.
But there is no way to go. If you upgraded from previous version to Build 10147, you can use the key below to activate it:

It should be noted that this key is only suitable. Upgrade installation, WZor and the following "test on the crowd" have been involved in the test, have already used personal experience to tell everyone.
