Windows 10 Microsoft tries to strike a balance for every kind of user

Yes, the Start menu is back. Yes, there are virtual desktops. No, the Charms bar hasn't gone away. And no, we don't know when Windows 10 will ship or what it will cost. But we've seen the technical preview of Windows 10 and the word to bear in mind for this release is productivity.
Microsoft's Joe Belfiore repeatedly emphasised that this is a very early build without even all the features that have been announced, and that there might be rough spots. We didn't see any problems in the time we had to try it out at Microsoft's San Francisco event, but what's clear is that there is plenty more to come.
This isn't the place to look for changes in Explorer or the control panel, let alone desktop tools like Paint and Notepad or Store apps like Music and Video. The technical preview is about the core features that are supposed to prove Microsoft can balance touch, mouse and keyboard without making any users feel abandoned.
