Prevent Manipulation of App Tiles on Start Screen

You can prevent manipulation of app tiles on the Windows Start screen by using Group Policy or the registry to disable user changes to the Start layout. This guide explains how to lock tiles in place, hide specific apps, and restore defaults if needed.

Why Lock the Start Screen?

On shared computers—school labs, library kiosks, or office workstations—users often drag, resize, unpin, or delete tiles, which disrupts the layout for everyone else. Locking the Start layout ensures that every sign-in shows the same tiles in the same positions, reducing support calls and keeping important apps visible. It also prevents users from accidentally removing critical shortcuts.

How the Lock Works

Windows treats the Start layout as a set of configuration files. When you apply a policy, Windows reads a layout file (XML or JSON) and applies it at sign-in. If the policy is set to enforce, any changes the user makes are reverted on the next sign-in. If set to apply once, the layout is set the first time, but users can modify it afterward. The policy also hides the Unpin from Start and Resize options in the context menu.

Method 1: Group Policy (Windows Pro/Enterprise)

  1. Press Win + R, type gpedit.msc, and press Enter.
  2. Navigate to User Configuration > Administrative Templates > Start Menu and Taskbar.
  3. Double-click Start Layout.
  4. Select Enabled, then enter the path to your layout file (e.g., C:\Layouts\start.xml).
  5. Choose Start Layout for the “Start Layout� setting and Enforce if you want to prevent changes.
  6. Click OK and restart the computer.

For Windows 10, the setting is Start Layout under the same path. For Windows 11, the policy is called Start Layout as well, but the file format is JSON.

Method 2: Registry (All Editions)

If you don’t have Group Policy (Windows Home), you can use the registry:

  1. Press Win + R, type regedit, and press Enter.
  2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Explorer.
  3. Right-click on the right pane, choose New > DWORD (32-bit) Value.
  4. Name it LockedStartLayout and set its value to 1.
  5. Create another DWORD named StartLayoutFile and set its value to the full path of your layout file (e.g., C:\Layouts\start.xml).
  6. Restart the computer.

To unlock later, set LockedStartLayout to 0 or delete both values.

Creating the Layout File

You can generate a layout file by:

  • On a reference computer, arrange the Start screen as desired.
  • Open PowerShell as an administrator and run Export-StartLayout -Path "C:\Layouts\start.xml" (Windows 10) or Export-StartLayout -UseDesktopApplicationLayout -Path "C:\Layouts\start.json" (Windows 11).
  • Copy the file to the target computers.

For Windows 11, the JSON file is more complex; the export command handles it automatically.

Common Problems and Fixes

  • Policy doesn’t apply: Ensure the file path is accessible to all users (put it in a shared folder with read permissions). Also, check that the policy is under User Configuration, not Computer Configuration.
  • Users can still change tiles: If you used Apply once, users can modify after first sign-in. Use Enforce to revert changes.
  • Layout file is ignored: The file must be valid XML or JSON. Test it with the export/import commands first.
  • Start menu is completely blank: If the layout file is missing or corrupted, Windows may show no tiles. Always keep a backup copy.

Alternatives to Locking

If you don’t want to fully lock the layout, you can:

  • Hide specific tiles: Use Start Layout policy to remove certain apps without locking the whole screen.
  • Use Kiosk Mode: For a single-app experience, set up Assigned Access in Windows 10/11.
  • Reapply on logoff: Use a logoff script to re-export the default layout.

Frequently Asked Questions

Does this work on Windows 11?

Yes, the Group Policy and registry methods work on Windows 11 Pro, Enterprise, and Education. Windows 11 Home lacks Group Policy, but the registry method works there too, as long as you create the layout file in JSON format.

Can users still open apps if tiles are locked?

Yes, locking the layout only prevents changes to the tile arrangement. Users can still open apps from the Start menu, taskbar, or desktop shortcuts.

How do I unlock the Start screen later?

In Group Policy, set the policy to Not Configured or Disabled. In the registry, set LockedStartLayout to 0 and delete StartLayoutFile. Restart the computer.

Will this affect the taskbar?

No, the Start Layout policy only affects the Start screen tiles. To lock the taskbar, you need a separate policy: User Configuration > Administrative Templates > Start Menu and Taskbar > Lock the Taskbar.

Can I lock only specific tiles?

Yes, the layout file can include only the tiles you want to show. Any tiles not in the file will be removed from the Start screen when the policy is enforced.

What if I don’t have a layout file?

You can create one manually by following the XML/JSON schema, but it’s easier to export from a configured computer. Microsoft provides documentation for the schema in the Windows IT Pro Center.
