Windows
7 Taskbar can be set to display on program icons only with all
additional tabs or icons combine into stack, or as a buttons with
application icon and label with each window has its own button on the
Taskbar. By default, the length or width of the button or icon on
Taskbar is fixed, and Windows 7 only allows user to change the size of
Taskbar pinned icons and buttons together with font to standard or
smaller.
With the following registry trick, user can also change
or adjust the width, or length of the buttons appear on the Windows 7
Taskbar. The hack has been used to simulate “not combine or stack but
hide labels” option to limit the width of buttons with label so that
label (text after the icon on button which normally takes the form of
window’s title) is hidden and the button is left with just the icon.
How to Adjust Button Length or Width Size in Windows 7 Taskbar
1. Run Registry Editor (RegEdit).
2. Navigate to the following registry key:
HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics
3. Right click on a blank space on the right pane, select New, then String Value. Name the new string value as MinWidth.
Note: If “MinWidth” already exists, skip this step.
4. Double click on “MinWidth”, and change the value data according to
the preferred size. By default, Windows 7 has the following MinWidth
value (estimated), when MinWidth is not defined or not created:
Button with standard or normal icons: 56
Button with small icons: 40
MinWidth
5. Restart the computer, or log off and log on again.
Note:
Above change button width trick only work when Taskbar is set to
display “button”, which mean it doesn’t work is Taskbar buttons’
behavior is set to “Always combine, hide labels”, where Windows 7 will
always use it default size for icon-only button.
