Windows 11 includes several security features that ensure your privacy and data safety. One of these is the automatic lock feature, which locks your PC after a set period of inactivity. When the system locks, users must re-enter their password, PIN, or biometric authentication to gain access again.
This is useful if you step away from your desk for a while or forget to lock your PC manually. Fortunately, Windows 11 offers multiple ways to enable auto-locking — including through system settings, Group Policy, or the Dynamic Lock feature that locks your device when you walk away with your paired smartphone.
Why You Should Automatically Lock Your PC
Before we go into the “how,” let’s understand why it’s crucial to use an automatic lock feature:
- Prevents unauthorized access: Ensures no one can snoop into your files when you leave your PC unattended.
- Protects sensitive information: Ideal for users handling work data, passwords, or personal documents.
- Complies with workplace security policies: Many organizations require an automatic lock period for compliance.
- Saves power: Locks often go hand in hand with sleep settings, conserving battery life.
- Adds a layer of privacy: Your open apps and documents stay hidden when the screen locks.
This article will guide you step-by-step through all major methods to automatically lock your Windows 11 PC after a time frame, ensuring your computer remains secure even when you’re not around.
Method 1: Use Screen Saver Settings to Auto-Lock PC
The easiest way to make Windows 11 lock automatically after a time frame is by enabling the screen saver lock. Here is how to do:
- Press
Windows + Rto open the Run dialog box. - Type control desk.cpl,,@screensaver and press Enter.
- This command directly opens the Screen Saver Settings window.
- In the window that appears, select a screen saver from the drop-down list (you can choose “Blank” if you don’t want any animation).
- Check the box On resume, display logon screen.
- Under Wait, set the number of minutes you want before your PC locks. For example, setting it to 5 minutes means your PC will automatically lock after 5 minutes of inactivity.
- Click Apply and then OK to save your changes.
Example:
If you set “Wait” to 10 minutes, and no keyboard or mouse input occurs during that time, Windows 11 will automatically activate the screen saver and lock the screen.
Why It’s Effective
This method is simple, works on all editions of Windows 11, and doesn’t require administrative privileges.
Method 2: Use Dynamic Lock to Lock PC When You Walk Away
Windows 11 includes a clever feature called Dynamic Lock, which automatically locks your PC when you (and your paired smartphone) move away from it.
How Dynamic Lock Works
Dynamic Lock uses Bluetooth to detect when your paired smartphone is out of range. If your phone disconnects, Windows waits about 30 seconds and then locks the PC automatically.
Steps to Enable Dynamic Lock:
Pair your smartphone with your PC:
- Go to Settings → Bluetooth & devices → Devices.
- Turn on Bluetooth on both your PC and your phone.
- Click Add device → Bluetooth and select your phone from the list to pair it.
Enable Dynamic Lock:
- Open Settings → Accounts → Sign-in options.
- Scroll down to Dynamic Lock.
- Check the box “Allow Windows to automatically lock your device when you’re away.”
Test it out:
- Walk away with your phone and wait about 30 seconds to 1 minute.
- Your PC should lock automatically once the Bluetooth connection drops.
Advantages:
- Hands-free and smart.
- Ideal for laptop users.
- No time configuration needed — locks automatically when you move away.
Limitation:
Dynamic Lock doesn’t let you set a specific time frame manually. It depends on Bluetooth signal loss, which may vary by distance and environment.
Method 3: Lock Automatically Using Power & Sleep Settings
You can make your PC lock automatically when it goes to sleep by adjusting your power and sleep settings.
Steps:
Open Settings by pressing Windows + I.
Go to System → Power & battery.
Under Screen and sleep, expand the section to adjust the timer.
Choose when your screen should turn off and when the device should go to sleep — for example:
- “On battery power, put my device to sleep after 10 minutes.”
- “When plugged in, put my device to sleep after 15 minutes.”
Once sleep mode is activated, ensure that password protection is required on wake-up:
- Go to Settings → Accounts → Sign-in options.
- Under Additional settings, enable “If you’ve been away, when should Windows require you to sign in again?”
- Select “Every time” from the drop-down list.
This ensures that your system locks automatically whenever it wakes up from sleep mode.
Method 4: Lock Automatically via Group Policy Editor (Windows 11 Pro & Enterprise)
If you’re using Windows 11 Pro, Enterprise, or Education, you can configure automatic locking using Group Policy Editor for better control.
Steps to Enable Auto Lock via Group Policy:
- Press
Windows + Rand type gpedit.msc, then press Enter. - In the left panel, navigate to:
Computer Configuration → Administrative Templates → Control Panel → Personalization - Double-click “Screen saver timeout.”
- Select Enabled and set the timeout value in seconds.
- For example, to lock after 5 minutes, enter 300 seconds.
- Click Apply → OK.
- Next, double-click “Password protect the screen saver.”
- Choose Enabled and click Apply → OK.
After applying these settings, your PC will automatically lock after the specified timeout period.
Method 5: Automatically Lock Using Registry Editor (Advanced Users)
If you prefer a technical approach, you can configure automatic locking through the Windows Registry. This method works on all editions of Windows 11 but should be handled carefully.
- Press
Windows + R, type regedit, and hit Enter to open the Registry Editor. - Navigate to the following path:
HKEY_CURRENT_USER\Control Panel\Desktop - On the right pane, find or create a new String Value named:
ScreenSaveTimeOut - Double-click it and enter the desired timeout value in seconds (e.g., 300 for 5 minutes).
- Create or edit another String Value named ScreenSaverIsSecure and set its value to 1.
- Finally, set or create SCRNSAVE.EXE with a valid path (e.g.,
C:\Windows\System32\scrnsave.scr). - Restart your computer or sign out and back in for changes to apply.
Your system will now lock automatically after the set time frame.
Method 6: Use Task Scheduler to Trigger Automatic Lock
For complete control, you can create a Task Scheduler rule that locks your PC after a specific idle time.
Steps:
- Press
Windows + S, type Task Scheduler, and open it. - Click Create Task on the right panel.
- In the General tab:
- Give it a name, e.g., Auto Lock Task.
- Check Run whether user is logged on or not.
- In the Triggers tab:
- Click New → Begin the task: On idle.
- Set the idle time (for example, 10 minutes).
- In the Actions tab:
- Click New.
- Under “Program/script,” type:
rundll32.exe user32.dll,LockWorkStation
- Click OK, then save the task.
Whenever your PC remains idle for the specified time, Task Scheduler will automatically lock it
Method 7: Third-Party Auto-Lock Utilities (Optional)
Several third-party utilities also help you automate the locking process with more customization. Examples include:
- AutoLock – Allows you to define inactivity time and automatically locks your screen.
- Smart PC Locker Pro – Lets you password-protect and schedule automatic locking.
- WinLock – Offers advanced session management and timer-based locking.
Note: Always download such software from trusted sources and scan with antivirus before installing.
Bonus Tip: Lock PC Instantly Using Shortcuts
While automatic locking is convenient, sometimes you may want to lock instantly. Here are some handy methods:
- Press Windows + L → Locks your PC immediately.
- Use Ctrl + Alt + Delete → Lock.
- Create a desktop shortcut:
- Right-click desktop → New → Shortcut.
- Type:
rundll32.exe user32.dll,LockWorkStation - Name it Lock PC and double-click it whenever needed.
Best Practices for Auto-Lock Settings
- Set the timer to 5–10 minutes for optimal balance between convenience and security.
- Use a strong password or PIN to secure your login.
- Combine with BitLocker encryption for additional data safety.
- Keep Dynamic Lock active for added mobility protection.
- Test your setup regularly to confirm the auto-lock feature works as expected.

Automatically locking your Windows 11 PC after a set time frame is one of the simplest yet most effective ways to keep your device secure. Whether you use Screen Saver Settings, Dynamic Lock, Power & Sleep, or Group Policy, each method ensures that your PC remains inaccessible to others when you’re away.
This security practice is essential for anyone handling sensitive or personal data. It adds a protective barrier against unauthorized access and keeps your files safe at all times.
