In Windows 7, how to show day name in system tray clock?

Without installing third-party software, how do I display the day in the clock in the lower-right system tray clock in Windows 7. For example: "Tuesday" (in addition to normal time and date display)

The only way I can think of is to change the date format.

• Open Control Panel->Clock, Language, Region->Change the date, time, or number format->Additional Settings...->Date tab
• Prepend dddd to the Short date: format

You'll then see the day name in the tray clock.

Of course, this will change the short date format throughout the OS, which may or may not be a problem for you.

Simply make the Taskbar a little bigger and it will display the date.

In addition, I am not sure, but will look up and see if there is a registry hack or alternative way to do it without stretching the bar.
