Microsoft working on Tabs feature in all programs in Windows 10

There is an excellent demand for tabs, especially in File Explorer, which may date back to when Windows 7 was released. It appears that the software giant may be working on this feature in the future. According to inside sources, Microsoft is working on a tabbed shell, which brings tabs to all Windows 10 applications, including Windows 10 File Explorer.
As per information, tabbed shell works at OS level so there is no need of developers to develop it separately. Tabbed shell works in Win32, UWP all kinds of applications.

Microsoft Edge is one of the UWP apps that offers tabs

Initial reports indicate that the tabbed shell closely resembles the tab styling of Microsoft Edge. The goal of the tabbed shell is to provide a new, user-friendly experience for the Windows operating system. However, there are potential conflicts that may arise with the tabbed shell, such as having multiple close or maximize buttons. We hope that Microsoft will make the necessary adjustments and refinements before releasing it to the public.

While some third-party applications offer similar interfaces, having tabs as a built-in feature would be quite exciting. The tabbed shell is expected to be included in the Redstone 3 or 4 updates, which are scheduled for release in late 2017 and 2018, respectively.</span></p>
