The new Microsoft Windows 10 Technical Preview is now available. You can’t officially direct download the software. Copies exist on torrent websites but their history is iffy and while I hate to diss the bittorrent community, there’s a high possibility you will not get what you’re looking for!
Or you can try http://preview.windows.com/ direct. You need to register to download the ISO (remember its over 2 GB) and without the Windows 10 Tech Preview you can’t contribute with feedback. This I think is unfair to Windows users who haven’t or can’t try the Preview yet want to send in their suggestions. If you know how do this without that do add your comments to this post.
Microsoft has also released videos (below) about this next generation. Enjoy (or foam at the mouth with rage):
