    how does upgrading to windows 10 build 10240 affect my activation

    i am going to use a product key for pro found here --> Download Windows 10 Insider Preview ISO File - Windows 10 Forums

    will that have an impact on my copy of windows, will it turn my genuine windows 8.1 copy into a not genuine windows 10 if i use that product key?

    Ah.. I upgraded from an activated copy of WIn8.1 to build 19249 and the new build remained activated and I wasn't required to use a key to accomplish this. This was done by using an ISO of 10240 to upgrade.
