Microsoft plans to introduce the Window Hopper feature in the PowerToys toolset, allowing Windows 10 and 11 users to quickly switch between multiple windows of the same application. Users need to install PowerToys from the Microsoft Store and enable the feature in the 'Windows & Layouts' settings. After that, they can press Alt+Backtick to cycle through the windows of the current application. This feature is specifically designed for multi-window work scenarios, such as browsers, terminals, File Explorer, and code editors, helping to avoid interference from other application windows and improve work efficiency.
