In today’s digital world, privacy and data security are more important than ever. Whether you’re using your PC for work, school, or personal projects, you likely have applications that you want to keep away from prying eyes. Fortunately, Windows 11 offers several ways to protect your apps from unauthorized access.
In this comprehensive guide, we’ll walk you through how to lock app in Windows 11 step-by-step — using both built-in features and third-party tools. By the end, you’ll know multiple effective methods to secure your apps and keep your data private.
🧭 What Does “Locking an App” Mean in Windows 11?
Locking an app means restricting access to it so that only authorized users can open or modify it. When you lock an app, you essentially add an extra layer of protection — similar to setting a PIN or password on your phone apps.
This can help you:
- Protect sensitive information (like financial apps or messaging platforms)
- Prevent kids or other users from accessing certain apps
- Increase overall system security
💡 Why You Should Lock Apps on Windows 11
Here are a few compelling reasons to secure your applications:
| Reason | Description |
|---|---|
| Privacy Protection | Keep your personal files, chats, and browsing data safe. |
| Workplace Security | Prevent unauthorized access to professional tools or documents. |
| Parental Control | Restrict children’s access to inappropriate or unsafe apps. |
| Data Safety | Protect financial and confidential apps from being opened accidentally. |
Simply put, locking apps is one of the easiest ways to enhance digital privacy and control who uses what on your PC.
🛠️ Methods to Lock Apps in Windows 11
Windows 11 doesn’t have a one-click “lock app” button, but there are several reliable ways to achieve the same result. Let’s explore each method in detail.
🪟 Method 1: Lock Apps Using the Built-in Family Safety Feature
If you share your computer with family members, Microsoft’s Family Safety feature is a great way to restrict app usage.
Steps to Lock Apps Using Family Safety
- Open Settings → Go to Accounts > Family & other users.
- Click Add a family member and follow the prompts to create a child account.
- Once added, sign in to Microsoft Family Safety at https://account.microsoft.com/family.
- Select the child’s profile.
- Go to App and Game Limits → turn on the App and game limits toggle.
- Choose the specific app you want to restrict and set time limits or block access entirely.
✅ Tip: This feature is perfect if you want to limit access for kids or other family members without using third-party apps.
🔒 Method 2: Lock Apps Using the Local Group Policy Editor
This method works for Windows 11 Pro, Enterprise, or Education editions.
Steps to Lock Apps via Group Policy
- Press Win + R to open the Run dialog box.
- Type
gpedit.mscand press Enter. - Navigate to:
User Configuration → Administrative Templates → System. - Double-click on Don’t run specified Windows applications.
- Enable the policy and click Show.
- Add the names of the apps you want to block (e.g.,
chrome.exe,spotify.exe). - Click Apply > OK, then restart your computer.
💡 This method completely blocks users from opening listed apps.
🧩 Method 3: Use AppLocker (Advanced Users)
AppLocker is a professional-level tool included in Windows 11 Pro and Enterprise that allows administrators to create detailed app restrictions.
Steps to Lock Apps with AppLocker
- Press Win + R, type
secpol.msc, and press Enter. - Go to Application Control Policies → AppLocker → Executable Rules.
- Right-click Executable Rules, and select Create New Rule.
- Choose Deny to block specific users from running the app.
- Click Browse Files to select the app’s executable (.exe file).
- Finish the wizard and apply the policy.
👉 AppLocker gives precise control — ideal for businesses or multi-user systems.
🔐 Method 4: Password-Protect Apps Using My Lockbox
My Lockbox is a free third-party software that lets you password-protect apps and folders easily.
How to Use My Lockbox
- Download and install My Lockbox from its official site.
- Launch the program and set a password for protection.
- Select the folder or app you want to lock.
- Click Lock — and it’s instantly hidden and inaccessible.
- To unlock, open My Lockbox and enter your password.
⭐ Great for everyday users who prefer a simple and visual interface.
🧱 Method 5: Lock Apps Using Folder Encryption
Another way to protect apps is to encrypt the folder where they’re installed.
Steps to Encrypt a Folder
- Right-click the app’s installation folder.
- Select Properties > Advanced.
- Check Encrypt contents to secure data.
- Click OK and Apply.
Now, only your Windows user account can access the encrypted folder. If someone logs in with another account, the app will be inaccessible.
🔑 Method 6: Use Folder Lock Software for Enhanced Security
Apps like Folder Lock or Easy File Locker provide professional-grade app and folder protection.
How to Use Folder Lock
- Download and install Folder Lock.
- Set up a master password during the first launch.
- Add the app’s folder to the protection list.
- Choose Lock, Hide, or Encrypt options as per your need.
- Save your settings.
These apps are especially useful for people handling sensitive files or financial tools.
🧭 Method 7: Set Up a Secondary User Account
Creating a separate Windows account can effectively limit access to certain apps.
Steps
- Go to Settings → Accounts → Family & other users.
- Click Add account → choose Local account if you don’t want Microsoft syncing.
- Assign apps and permissions accordingly.
- Sign out and let others use the secondary account without admin rights.
This approach ensures your main account — with all apps and files — remains private.
🧰 Method 8: Lock Apps with Windows Hello
Windows Hello provides biometric and PIN-based login options for app-level protection.
Some modern apps, such as OneDrive or Microsoft Edge, support Windows Hello authentication directly.
How to Enable It
- Open Settings → Accounts → Sign-in options.
- Set up a PIN, Fingerprint, or Facial Recognition method.
- Open an app that supports Windows Hello → follow its security setup.
Whenever you reopen that app, it’ll prompt for your Hello credentials.
🧠 Method 9: Use the Registry Editor (Advanced)
Warning: Editing the registry incorrectly can cause system issues. Proceed carefully.
Steps
- Press Win + R, type
regedit, and hit Enter. - Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer - If the Explorer key doesn’t exist, create it.
- Right-click → New > DWORD (32-bit) Value → Name it
DisallowRun. - Set its value to
1. - Create a new subkey named DisallowRun.
- Add new string values for each app you want to block (e.g.,
1 = notepad.exe).
Restart your PC, and the selected apps will be blocked.
🧾 Method 10: Use App Privacy Settings
Windows 11 lets you manage app permissions easily.
Steps
- Go to Settings → Privacy & Security → App permissions.
- Choose the app category (e.g., Camera, Microphone).
- Turn off access for apps you want to restrict.
This doesn’t “lock” the app completely but limits its access to system resources — boosting privacy.
📱 Bonus: Use Microsoft Store App Locker
If you’re mainly using Microsoft Store apps, you can manage them directly:
- Open Microsoft Store → click your profile picture → App settings.
- Use PIN or Windows Hello to protect your Store access.
- Lock apps under Family Safety → App limits.
