1. Right-click on the Taskbar, and in the popup menu that appears, select "Properties".
2. In the Taskbar and Start Menu Properties dialog box that appears, select the Taskbar tab if not already selected.
3. On the Taskbar tab, click to uncheck the  Group similar taskbar buttons checkbox.
4. Click the [Apply] or [OK] button to apply the configuration change.
