If disabled, taskbar buttons will be set to always never combine, and the Combine taskbar buttons and Combine button on other taskbars settings will be grayed out. If you like, you can prevent the grouping of taskbar buttons in Windows. As more apps and windows open, buttons get smaller, and eventually the buttons will scroll.

Never combine - This setting shows each window as an individual, labeled button, and never combines them, no matter how many windows are open.

Clicking the button displays a list of the windows that are open. When the taskbar becomes crowded, apps with multiple open windows collapse into a single app button.

Combine when taskbar is full - This setting shows each open window as an individual, labeled button.

Each app appears as a single, unlabeled button (icon), even when multiple windows for an app are open.

Always combine, hide labels - This is the default setting.

If you have multiple displays, then you will be able to set button grouping separately for the main taskbar and other taskbars.

You can make the taskbar look how you want, manage your calendar, pin your favorite apps to it, change the size, change location on screen, and specify how taskbar buttons group together when you have more than one window open.

You can also see the date and time, system icons, and items running in the background on the notification area. The taskbar allows you to find, see, open, and switch between your apps. Windows includes a special application desktop toolbar called the taskbar that shows on the bottom of a display screen by default. How to Enable or Disable Grouping of Taskbar Buttons in Windows
