This one isn’t so much a secret feature of Windows 10 as much as the primary reason you might want to try out the preview. Microsoft has created a feedback app specifically for users of this Technical Preview. While using the OS, Windows will occasionally ask you for feedback for certain features, but you can also leave your own.
If you’ve ever complained in a comment thread or written a twenty-paragraph article venting frustration over Windows (I’m guilty of both), now’s your chance to let them know exactly how you’re feeling. It’s not uncommon for Microsoft to solicit feedback from a beta, but the system for submitting input is incredibly easy, so it’s worth mentioning on its own. There’s never been a better time to tell Redmond what you want.
All-in-all, Windows 10 is already a pretty solid improvement over Windows 8, and we can already see that new features are coming. There are also a wealth of Metro-style apps that, while technically not new, are worth exploring now that they’re not locked in a cumbersome full-screen mode. As an example, the Photos app contains some pretty sweet photo editing features, similar to what you might find on a phone. Time will tell what else is new, but for now there’s plenty of cool new toys to play around with.
