Basic PC troubleshooting

Basic PC problem #4

When you are using your PC and something goes wrong such as freezing the application you use or some new window pops-up and you are trying hard to back it to normal. There's an easy way to kill those unwanted pops-up.

First, from your keyboard, press Ctrl+Alt+delete.
Second, new window will pop-up appearing all active application running in your system including those unwanted application.
Third, just delete the unwanted application.
Forth, you're done. You made it, your system now is running back to normal.

Good luck. Please leave me a comment.
