How To Lock Windows 11 Apps

People are currently reading this guide.

Alright, let's dive deep into the world of securing your Windows 11 applications! Have you ever wished you could add an extra layer of protection to specific apps on your computer, preventing unauthorized access even when your main user account is logged in? Well, you're in the right place! This comprehensive guide will walk you through various methods to achieve just that, with step-by-step instructions to make the process crystal clear.

Step 1: Understanding the Landscape of App Locking in Windows 11

Before we jump into the "how-to," it's important to understand that Windows 11 doesn't have a built-in, straightforward feature to lock individual applications with a separate password like you might find on a smartphone. However, don't fret! We can achieve a similar level of security by leveraging other features and third-party tools. Think of it as being a digital detective, using different clues and tools to reach our desired outcome.

Why Lock Apps? You might be wondering why someone would want to lock individual applications on a desktop operating system. Here are a few compelling reasons:
- Privacy: If you share your computer with family or roommates, you might want to keep sensitive applications like email clients, banking apps, or personal photo galleries private.
- Security: Preventing unauthorized access to certain applications can safeguard important data and prevent accidental or malicious actions.
- Child Safety: Parents might want to restrict access to certain games or online browsers for their children.
Our Toolkit: In this guide, we'll explore several approaches:
- Using the Dynamic Lock feature for automatic locking.
- Leveraging third-party application locking software.
- Exploring the potential of creating separate user accounts.
- Utilizing Group Policy Editor (for Pro, Enterprise, and Education editions) to restrict application access.

Let's start with a relatively simple built-in feature!

Step 2: Utilizing Dynamic Lock for Automatic Locking

Dynamic Lock is a Windows feature that automatically locks your device when you step away from it, provided you've paired it with your phone via Bluetooth. While it locks the entire system rather than individual apps, it's a good first line of defense and ensures that when you're not physically present, no one can access any of your applications.

Sub-step 2.1: Pairing Your Phone via Bluetooth

Click on the Start button (the Windows icon on the taskbar).
Select the Settings icon (it looks like a gear).
In the Settings window, click on Bluetooth & devices in the left-hand sidebar.
Ensure that Bluetooth is toggled On.
On your smartphone, make sure Bluetooth is also enabled and it's discoverable.
Back on your Windows 11 PC, click on Add device.
Select Bluetooth.
Your PC will start scanning for nearby Bluetooth devices. Once your phone appears in the list, click on it to initiate the pairing process.
You'll likely see a PIN code displayed on both your computer and your phone. Verify that the codes match and then click Pair on both devices.
Once paired, your phone will be listed under "Paired devices" in the Bluetooth & devices settings.

Sub-step 2.2: Enabling Dynamic Lock

In the Windows Settings app, navigate to Accounts.
Click on Sign-in options.
Scroll down until you find the Dynamic lock section.
Check the box next to "Allow Windows to automatically lock your device when you're not around".

Now, when your paired phone moves out of Bluetooth range of your computer, Windows will automatically lock, securing all your open applications. While not a specific app lock, it's a valuable security measure.

Step 3: Exploring Third-Party Application Locking Software

For more granular control – locking specific applications – you'll likely need to turn to third-party software. Several reputable applications are designed for this purpose.

Sub-step 3.1: Researching and Choosing Software

Search Online: Use a search engine to look for "Windows application locker" or "password protect Windows apps."
Read Reviews: Look for reviews and ratings of different software to gauge their reliability, security, and ease of use. Consider factors like:
- Security Strength: How robust is the password protection?
- User Interface: Is it easy to understand and use?
- Performance Impact: Does it slow down your system?
- Cost: Is it free or paid? If paid, is the price reasonable?
Download and Install: Once you've chosen a software, download it from the official website of the developer. Be cautious of downloading from untrusted sources. Follow the installation instructions provided by the software.

Sub-step 3.2: Configuring the Software

The exact steps will vary depending on the software you choose, but generally, you'll need to:

Set a Master Password: This password will be used to access the application locker itself and to lock/unlock other applications. Choose a strong and unique password.
Select Applications to Lock: The software will typically present a list of installed applications. Select the ones you want to password-protect.
Configure Locking Options: Some software might offer options like:
- Automatic Locking: Locking apps when they are closed or after a period of inactivity.
- Password Prompts: Customizing when and how the password prompt appears.
- Security Features: Options like hiding the locked application window or preventing it from being closed via Task Manager.

Remember to carefully follow the instructions provided by your chosen third-party application.

Step 4: Leveraging Separate User Accounts

While not directly locking individual applications within a single logged-in session, creating separate user accounts in Windows provides a strong form of isolation. Each user account has its own files, settings, and applications.

Sub-step 4.1: Creating a New User Account

Press the Windows key + I to open the Settings app.
Click on Accounts.
Select Family & other users.
Under "Other users," click on Add account.
Follow the on-screen instructions. You can choose to add a Microsoft account or a local account. For better security and synchronization, a Microsoft account is generally recommended.
Set a strong password for the new user account.

Sub-step 4.2: Using Separate Accounts for Different Purposes

You can now use your primary account for general tasks and log in to the new account only when you need to use specific applications that you want to keep private from other users of the computer. This ensures that the files and data associated with those applications are only accessible when the correct user account is logged in.

Switching between user accounts is relatively quick and doesn't require closing all your applications in the other account. Press Windows key + L to go to the lock screen, and then you can select a different user to log in.

Step 5: Utilizing Group Policy Editor (For Pro, Enterprise, and Education Editions)

If you are using a Pro, Enterprise, or Education edition of Windows 11, you can use the Group Policy Editor to restrict access to specific applications for certain users. This method is more advanced but offers a powerful way to control application access.

Sub-step 5.1: Accessing the Group Policy Editor

Press the Windows key + R to open the Run dialog box.

Type gpedit.msc and press Enter. This will open the Local Group Policy Editor.¹

Sub-step 5.2: Restricting Application Execution for Specific Users

In the Group Policy Editor, navigate to the following path in the left-hand pane: User Configuration > Administrative Templates > System
In the right-hand pane, find and double-click on the setting "Don't run specified Windows applications".
In the "Don't run specified Windows applications" window, select "Enabled".
Under "Options," click on the "Show..." button.
In the "Show Content" dialog box, under the "Value" column, enter the executable name of the application you want to block (e.g., chrome.exe for Google Chrome). Enter each application on a new line.
Click OK on both the "Show Content" and "Don't run specified Windows applications" windows.

Sub-step 5.3: Applying the Policy to Specific Users (Optional)

The above steps will apply the policy to all users on the computer. To apply it to specific users, you would typically configure this within a domain environment using the Group Policy Management Console (GPMC). For local users, you might need to create a specific user group and then configure the policy accordingly, which is a more advanced process.

Be cautious when using the Group Policy Editor, as incorrect configurations can lead to unexpected behavior on your system.

Step 6: Best Practices and Considerations

Strong Passwords: If you're using third-party software, always choose strong, unique passwords for locking your applications and the master password of the software itself.
Software Reliability: When choosing third-party software, stick to reputable developers and read reviews carefully to ensure the software is secure and doesn't contain malware.
Regular Updates: Keep your operating system and any third-party security software updated to benefit from the latest security patches.
Consider the Trade-offs: Each method has its pros and cons. Dynamic Lock is convenient but locks the entire system. Third-party software offers granular control but relies on external applications. Separate user accounts provide strong isolation but require switching accounts. Group Policy offers powerful control but is more complex. Choose the method that best suits your needs and technical comfort level.
Be Mindful of Accessibility: If other users of your computer rely on assistive technologies, make sure that any app locking methods you implement don't inadvertently hinder their access.

And there you have it – a detailed exploration of how to enhance the security of your Windows 11 applications! While a direct "lock this app with a password" feature isn't built-in, these methods offer effective ways to achieve a similar level of protection.
