Adjusting Windows Task bar size: InWindows 7

In Windows 7, the usual size of the Windows Taskbar is a bit
larger than usual. This takes some extra space at the bottom of the
computer screen. This makes selecting the applications easier as
the buttons are bigger. However for those who are using smaller
screens this may be a bit annoying as it takes more space on the
screen. If you want you can make the size of the taskbar smaller
by following the steps below.
1. In a blank space in the taskbar right click and select properties.
2. You will see the ‘Taskbar and Start Menu Properties’ dialog box
with many tabs.
3. Here click ‘Use small icons’ and select it.
4. Now click OK and close the dialog box.
Now the task bar will occupy smaller space. If you want you can
also hide the task bar when not required. If you want to hide the
task bar, in step 2 above, select the ‘Taskbar’tab, and in ‘Taskbar
appearance’, select ‘Autohide the taskbar’. If you choose this, if
you bring the mouse to the bottom of the screen the taskbar will
appear and if you move away from the task bar, it will be hidden.
