Alt + Tab is useful for switching between windows, but it cannot help you find that browser tab that you had opened in one of your windows. Soon, Windows 10 will show all open Edge browser tabs next to its windows.
When this change is available, you can use the new Microsoft Edge browser normally. When Alt + Tab, all browser tabs will appear as their own thumbnail, just like their own browser windows.

You do not like this? It’s okay. Microsoft says you can disable it from Settings> System> Multitasking. You can also configure it to only show your last three or five browser tabs so that tab overload doesn’t tarnish your Alt + Tab switch.
This feature is only for Microsoft Edge at the moment, but we could easily see it in other web browsers. Edge is based on the same Chromium code that forms the Chrome base, for example: Google could also enable this feature in Google Chrome. It is easy to see that Mozilla Firefox also takes advantage of it.
The Windows 10 Alt + Tab switch previously included all the tabs based on the Sets feature, but Sets never made it to a stable version of Windows 10. It seems that these tabs in Alt-Tab will only reach web browsers for now.
Microsoft revealed this feature on July 1, 2020. It is part of an Insider build of Windows 10 and requires Microsoft Edge 83 or newer. It probably won’t arrive on a stable version of Windows 10 until at least November 2020.
This is just one of the many cool features found in the Windows Insider build from July 1 (version 20161). Microsoft is also making Windows 10 tiles match their light or dark theme much better and enhancing the tablet experience on 2 in 1 devices.
