To get a feel of what's coming, Microsoft opened up a 'Technical Preview' from Oct. 1. This move aimed at PC analysts and experts will also help Microsoft to tweak and make further improvements before it gets to the market in 2015. A featured Windows Feedback app will send your views and opinion back to the company.

A note of advice: if you want to experiment with Windows 10, Microsoft recommends not using your primary PC for the install. As the software is unfinished, the install is best carried out on a secondary PC to avoid problems and data-loss. Pease follow the notes from Microsoft closely on Before you install Windows Technical Preview carefully before going further.
