This was one of the most silliest task that happened to me accidentally some time back. The problem was that whenever I press ctrl+alt+del to open Task Manager it opens but without the other tabs incorporated but only with the default window and its standard bar also seems missing. As i don’t know what caused this to happen, all the other things working fine so there may not be any virus attack.

Then from the Google search i found that this was very simple and funniest things we can do with Task Manager. Double clicking the left button of the Mouse anywhere on the border area of the task manager (look from the image attached) will do it.

It was so simple task that makes me to look like a fool but was really enjoyable… as may be i have clicked twice earlier which has caused to disappear the tabs.
