Hello everyone i need your help, i just install win 8.1 build 9471 but i can not activate it with any tools, so pls i need your help in advance. Thank you.
He means the product key. As for which serial he is talking about, I do not know. I do not play with the preview editions.
Why pothering with activating these preview/beta versions. You should only just try and test it until the release of the RTM version. Don't wast your time trying to activate it as it's not intended for the reliable use as M$ said these versions are for professional and developers to test not to rely on. Happy testing
And there also those users who try and/or begging to remove the watermark (question: WHY?) which is a reminder that those Preview version is just that: A Preview, time limited and time bombed! And those are also the users who'll start complaining after the time is run out!
