Microsoft is changing how Alt-Tab works on Windows 10

Microsoft's next big update to Windows 10, codenamed "Redstone 5," has been in testing for a few weeks, and the company is now ready to reveal some of the new features it's experimenting with. Along with the new features feature for all Windows 10 applications, Microsoft is also changing the way the Alt-Tab function works. Instead of tabulating between applications, Microsoft is experimenting with allowing Windows 10 users to also switch between tabs within the Sets feature within the Alt-Tab interface.

Microsoft has not reviewed its Alt-Tab task switch for years, and this feels like a great addition. Essentially, it means that Alt-Tab will now work for applications and browser tabs or application tabs. Microsoft is also working on bringing groups of applications with tabs to Timeline, its new Windows 10 feature that maintains a history of activities and web pages.




Microsoft seems to be betting on Timeline for productivity in Windows and all devices, and the company will extend this feature to both iOS and Android. The Microsoft Android Launcher will include Timeline so you can quickly collect web pages on the fly, and the Microsoft Edge browser on iOS will include access to Timeline.

Microsoft will begin testing these changes shortly with Windows Insiders, but there is no guarantee that they will all be sent with the next major Windows 10 update. Joe Belfiore of Microsoft made it clear in Build today that the company will only ship your Sets feature once it's ready, and that same approach applies to other Windows 10 features like "Your Phone".
