That you have to open the Activation forcibly an account with Microsoft has enabled only verschlimmbessert, but is stop MS Product Policy. You are the key, this has to be the MS account and then you can activate the product by entering the address e-mail. Unfortunately, it works quite not always quite as straightforward as it should. Once the key is associated with online and here there is an error on the MS site (which like to occur), it can not be re-entered. The product emerged then in the activation of the account list, however not on and then starts an ordeal by Microsoft kinds hotlines, which all do not feel responsible. The problem seems to want no one there to solve. After hours you hopefully luck and caught an employee who then opened a ticket yet. However, after more than 2 months there was still no response from the support! The trial period has expired and the product is therefore not really usable. License is thus apparently in the bucket.
