How to Shut Down Your Computer & Fix Frozen Programs: Windows Guide for Beginners

To shut down your computer, close all open windows, click the Start button on the Windows taskbar, and choose a power option — Shut down or Restart. This is the safe, standard method that lets Windows close background processes and save settings before the machine powers off. Every open window can be closed using the button in its upper-right corner.

Some applications run in full-screen mode, where the window-close button is not visible. In this situation, press the "Alt" and "Enter" keys at the same time to switch the application into windowed mode. Once it is in a window, you can close it like any other window before shutting down.

What is the correct way to shut down a Windows computer?

The correct way to shut down a Windows computer is through the Start menu rather than the power button, because this gives the operating system time to finish writing data to disk and close programs cleanly. Follow these steps:

1. Save your work and close all open documents and applications.
2. Click the Start button on the Windows taskbar.
3. Open the power menu (the power icon in the Start menu).
4. Select "Shut down" to turn the computer off completely, or "Restart" to reboot it.
5. Wait until the screen goes dark and the system unit's lights switch off before unplugging anything.

Choosing "Shut down" closes Windows fully and powers the machine off, while "Restart" closes Windows and immediately starts it again. Use Restart after installing software or updates that ask for a reboot, and use Shut down when you have finished working for the day.

Emergency shutdown

An emergency shutdown is needed when a computer crashes and stops responding to any user action — a state commonly described as the computer having "frozen". When this happens, press the "Ctrl", "Alt" and "Delete" keys at the same time. This key combination interrupts the current session and gives you a way to regain control without cutting the power.

Pressing "Ctrl", "Alt" and "Delete" brings up the Windows Task Manager, where you should open the "Applications" tab. The Task Manager lists every running program, so you can see which one has stopped responding and deal with just that application rather than the whole system.

Selecting the "End Task" button terminates the application highlighted in the dialog box and closes the window in which it was running. This option is useful in two cases: when the computer has frozen, and when you simply do not know how to exit an application through the normal method provided by its developers.

If you close the Task Manager window instead, you can choose not to interfere at all, and the system returns to the state it was in before you pressed "Ctrl", "Alt", "Delete". This is the so-called emergency shutdown — it lets you back out safely if the program recovers on its own.

When should you restart the operating system?

Restart the operating system only when the computer no longer responds to other user actions, because a reboot carries some risk to your data. When the operating system restarts, an error-correction program (ScanDisk) starts automatically. If ScanDisk detects errors it repairs them with almost no input from you, but in some cases part or even all of the information stored on the computer can be lost.

Because of that risk, treat rebooting as a step you take after gentler options — such as closing a single frozen program in Task Manager — have failed. A clean restart through the menu is always preferable to an abrupt power cut whenever the machine still responds at all.

Turning the computer off with the power button

As a last resort, you can turn off the computer by pressing the "Power" button on the system unit when nothing else works. This is the most forceful option and should only be used when the machine ignores every other action. When you switch the computer back on afterwards, the error-correction program (ScanDisk) runs and clears up the errors caused by the abrupt shutdown.

The probability of losing information with the power button is higher than with a normal reboot, because programs are stopped without any chance to save. For that reason, it is better to contact a specialist before pressing the "Power" button if the data on your computer is important and you are unsure what caused the freeze.
