Hello; First and foremost I want to say that this is theoretical. I do not know if it will work, and am only posting to see your opinion on this. If you want to test it out for yourself, more power to you. Please let us know how it goes. Consider the following : 1. Windows 8 does not come with a "trial" period the same way Win7 did. However, when you create an AIO .ISO, this 30 day "trial" period functionality is restored. 2. "Adding new features" by means of a Media Center Pack replaces the original key used. Now, Assume we are dealing with a fresh Windows 8 Pro install (from an AIO ISO) that is currently in the 30 day "trial" period. The key used would be a trial key (this is assumed, please correct me if this is NOT the case, as this is untested). If we "Added New Features" and typed in the key from a WMC Pack, that key would overwrite the trial key, and fully activate the OS for $9.99. ^This is half suggestion and half question. I haven't tested and don't know too much about Windows activation. If anyone has some insights as to whether or not that would work (or why it would not work if it wouldn't), it would be appreciated. I think something similar happened with KMS activators when the WMC pack was being given away for free, but again, I don't have any of the answers Thoughts, Ideas, and experiment results welcome! ~Diatech The post is meant for educational purposes only.
