What Are The Commands To Lock A Windows 10 Computer


You can easily lock your Windows 10 computer with just a few commands. Mastering how to lock your screen is important for keeping your data safe and secure from unauthorized access.

One of the easiest ways to lock your computer is by pressing the ‘Windows + L’ key combination on the keyboard. This will immediately lock your screen and you will be prompted to enter your credentials in order to gain access.

Another way is using the ‘Ctrl + Alt + Del’ command, which will open a menu where you can choose ‘Lock’ or ‘Sign Out’ options. Once selected, this will also take you directly to the login page where you must authenticate yourself before continuing.

To make it even easier, Windows has an option called ‘Fast User Switching’, which allows users to switch between different accounts without having to log out completely.

6 Commands to Lock Computer

1. Control + Alt + Delete 

Press Ctrl + Alt + Delete to access security options and quickly take action. This is the most commonly used option for locking a PC on Windows 10, and it grants you several key advantages:

With Ctrl + Alt + Delete, locking a Windows 10 computer couldn’t be simpler – no matter what level of experience you have with the operating system.


Now let’s move on to another way we can quickly lock our computers; the ‘win + l’ shortcut.

2. Use Win + L Shortcut

With a quick keystroke, you can quickly secure your device. Windows 10 offers an easy way to lock the screen with just two keys: Win + L. This shortcut will immediately lock the computer and require a password for access.

To use this method, press and hold down the Windows key (located between the left Alt and Ctrl keys on most keyboards) then press and release the “L” key. Your computer should lock in an instant, displaying a login screen which requires you to enter your password before access is granted.


This shortcut offers great convenience for those times when you need to step away from your machine but don’t want anyone else accessing it without your permission. It is also very fast – no more waiting several seconds while the screen locks!

Using this simple shortcut provides peace of mind knowing that all of your data remains secure until you return. With its ease of use, there’s no excuse not to take precautions against unwanted intrusions into your personal information when stepping away from your machine for even a moment. So remember: When leaving, just press Win + L at the same time – it’s that easy!

3. Lock Using Task Manager (CTRL + SHIFT + ESC)

Disconnecting your user account with Task Manager is a quick and easy way to secure your device. Using this method, you can lock the screen without signing out from the current session. Here are the steps:

  1. Open Task Manager App
  2. Right click on username in ‘Users’ tab
  3. Select ‘Disconnect’ from the menu
  4. Confirm by clicking ‘Disconnect User’ button
  5. Screen will be locked and taken to logon screen


Keeping your computer secure is important for protecting sensitive data. With Task Manager, you can quickly lock your device with minimal effort and no loss of data. This method provides a great alternative when you don’t have access to Win + L shortcut or Start Menu option.

4. From Start Menu (Windows Key)

You can easily lock your device from the Start menu. To do this, simply click on the Start button located in the lower left corner of your screen and then select your account profile icon.

Once you are here, you will see an option to ‘Lock’. Clicking this option will lock your computer’s screen.

This is a quick and easy way to lock your device without having to use any additional commands or programs.

It is important to always remember to lock your device whenever it is not in use as it helps protect it from unauthorized access.

With just a few simple steps, you can keep all of your data safe and secure while keeping prying eyes away from sensitive information.

5. Windows Terminal (Windows key + R and type cmd)

Using the Windows Terminal app, you can quickly secure your device.

All you need to do is open the app and type in the following command: ‘rundll32.exe user32.dll,LockWorkStation’.

This will immediately lock your computer’s screen, so no one else can access it until you enter your login credentials upon returning.


It’s a quick and easy way to keep your data safe from prying eyes without having to go through the Start Menu.

Additionally, after running this command, when you log back in again, you’ll be greeted with the Windows Terminal app instead of the desktop background or lock screen image that normally appears when locking a Windows 10 computer.

6. Use Run Prompt (Windows key + R)

Opening the Run prompt is an alternate way to securely secure your device. To open the prompt, press “Win + R” and paste in the command: rundll32.exe user32.dll, LockWorkStation. When you hit ‘OK’, it will lock your Windows 10 computer, making sure no one accesses it without permission.

This process has several advantages over using Windows Terminal:

  • It’s faster and more efficient.
  • You don’t need to open a separate window.
  • You don’t need any additional software or downloads.

It’s also very easy for anyone to use, which means that even those with little experience using computers can quickly and easily lock their devices when necessary.

Once you’ve done this once, you can create a desktop shortcut for locking the PC. This way, it only takes one click from anywhere on your computer to lock it up tight again.
