You are having trouble closing a program. You have tried to hit the Close button, the keyboard shortcut to close the program, and closing it from the taskbar. Before shutting down your computer, what other troubleshooting steps could you try?

You can open the version of your computer or device from the task manager to see the running programs and close the application

Explanation:

Right-click on the Windows Start menu and choose Task Manager (another way to open it is to press the keyboard shortcut Ctrl + Alt + Delete and select it from the options that appear).

NOTE: Click here if you don't know how to display Windows 8 Start.

You will see the main Administrator window (as in the image above). Displays a list of the programs that are currently running.

Find the application or process you want to close. Click on it with the RIGHT button and choose End task. In some cases a notice appears asking you to confirm it. Read what it says to know the consequences of forcing it. Confirm if you are determined to do so.

IMPORTANT:

There are viruses, adware or other spam programs that you may not be able to close even in this way. For these cases follow this link on how to clean viruses without entering Windows.

When you're done you can exit the Task Manager window. Click here to close background applications.
