Win10 set the method of clicking the taskbar program icon to switch windows

Then if you need to switch windows, you need to move the mouse to the program icon. When the preview window is displayed, click the preview window to complete the window switch. This way of switching windows is a bit cumbersome. So share a trick today, without having to wait until the preview window is displayed, just click on the program icon in the taskbar to switch windows. Here's how:
Open the Registry Editor and navigate to
HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Explorer/Advanced
Note: It is recommended to back up the registry before editing (how to back up the registry)

Then create a new DWORD (32-bit) value called LastActiveClick in the right window, double-click LastActiveClick, and change the value data to 1 in the open edit window.
Close the Registry Editor and restart Windows Explorer.
Then you open multiple windows of the same program, such as multiple IE browser windows. At this time, just click the IE icon in the task bar to switch between different windows without having to display the preview window.
