What is the computer Activity task area

Active Task Area

On the active task area, the button color of the current window is slightly darker than the other buttons, and the other icon button is raised, and it is concave in shape. Maybe now you have to ask, since it is the 3 icon button, why say "indicates that the user is now running (or open) more than 3 programs (or documents)." So you take a closer look at the "Notepad" button, this button is different than the other buttons, which is a small white inverted triangle on the right side of the button, which means that the Notepad document has more than one open (a yellow number appears after the Notepad icon opens a few documents),

Because Windows XP has a "Group similar taskbar button" feature, it will combine all the documents opened with the same program into a taskbar button, if you want to switch these Notepad window, click on the white inverted triangle, click on a menu will pop up, which is the full list of documents, Click the document you want to manipulate to switch the document window to the current window. Click on the icon to represent its button, the screen will appear on the Run window, the operation of the current window to switch is completed.

The taskbar can move anywhere, but in a locked state, the taskbar cannot be moved. Right-click the taskbar, after you remove the hook next to the lock taskbar, you can drag the taskbar to the left or right side of the desktop, drag the taskbar to the new location, and then click the Lock Taskbar on the right-click menu of the taskbar to lock it again.
