How to Auto Lock Windows 10 After Inactivity🔐 (GPO)

Using GPO or Registry, you can configure Windows to auto lock itself after inactivity or a user not using the computer for some time. Here’s how.

You can lock a Windows PC in a number of ways. Though not hard, locking Windows 10 is still a manual action. If you want to, you can configure Windows 10 to lock automatically after inactivity. You can specify the inactivity time like ten minutes, fifteen minutes, etc. If you find yourself frequently moving away from your computer then auto-locking Windows is quite useful and secure too.

In this quick guide, let me show the procedure to auto lock Windows after inactivity.

Steps to Auto Lock Windows 10 After Inactivity

The easiest way to make Windows 10 lock itself is to use the Group Policy editor. In the editor, you change a single policy and you are done. Do keep in mind that this method only works on pro and enterprise versions of Windows 10. If you are using Windows 10 home version then follow the second method. i.e, registry method.

Enable Windows Auto Lock After Inactivity via GPO

  1. Open the Start menu.
  2. Search and open “gpedit.msc“.
    Group policy start menu search
  3. In the GPO Editor, go to the following folder.
    Computer Configuration → Windows Settings → Security Settings → Local Policies → Security Options

  9. Reboot Windows.

After restarting, the policy will be applied. From now on, the computer will lock itself after the specified inactivity time.

To disable auto lock, just set the seconds value to 0 or empty in step 5 and save the changes.

Registry Method to Automatically Lock Windows 10 After Inactivity

If you are using Windows 10 home version, then you need to use the registry editor to automatically lock the computer. All you have to do is create a single value. Though editing registry for this specific purpose is nothing hard, I’d recommend you to backup the registry. The backup allows you to restore the registry if anything bad happens.

1. First, open the start menu, search for Registry Editor and press the enter button to open it.
