Only similar taskbar buttons will group together. If you uncheck the "Group
similar taskbar buttons" option in the Taskbar and Start Menu Properties,
you can then select the taskbar buttons you want to tile on your screen by
holding down the Ctrl key while selecting the tabs with your mouse then
right click one of the selected tabs and choose one of the options from the
menu.
If that doesn't answer your question, I would suggest that you reword your
question and post again because it is difficult to understand your question.
