If you only want to close a few specific applications, creating a batch file can automate the process of closing them all at once.

Open the Notepad application and enter the following command for each application you want to close.

taskkill /IM appname.exe /F

Replace appname.exe with the name of the application you want to close , such as notepad.exe, chrome.exe, winword.exe, etc.

Then you need to save this file with.bat extension. Finally double select this file to execute. All specified applications will be closed immediately.

Close multiple windows of an application

Right-select the application icon on the taskbar and select Close all windows .

Use Alt + Tab

Alt + Tab helps you observe all open application windows, but we still close them manually, which is to select the x icon.
