Windows Task Manager Displays without Menu, Title Bar, Tabs, and Close Button

Introduction

 
Today, I've faced a particular issue in my Vista machine. While trying to kill the process in Task Manager, I've faced a peculiar nature of task manager. Except for process screen(below), everything vanishes and I've tried a lot to fix up this issue but ended with no clue... OOPS.. too peculiar issue.

How to reproduce?
 
Double click on the border (Gray portion) of the Task Manager, you are able to get the above peculiar window.

Solution
 
The Task Manager switches to “Tiny Footprint Mode” when you double-click the gray area in the border around the tabs. You can switch back just as easily by double-clicking the gray area around the outside of the frame. Not very intuitive but at least there's nothing wrong with Windows or my machine.
