How to Remove Test Mode Watermark from Windows 10 Desktop

If you’re seeing the “Test Mode” watermark on your Windows 10 desktop, it indicates that your system is running in a special testing mode, often used for development or troubleshooting. While this mode can be useful for developers, most users want to remove this watermark to restore a normal appearance and ensure their system is running in standard mode. Removing the Test Mode watermark can also help improve your system’s professionalism and avoid potential confusion or suspicion about your PC’s security status.

What You’ll Need

• Administrative access to your Windows 10 PC
• Basic familiarity with Command Prompt or PowerShell
• Optional: Backup of your system (recommended before making system changes)

Step-by-Step

1. Open the Command Prompt as an administrator. To do this, right-click the Start menu and select “Command Prompt (Admin)” or “Windows PowerShell (Admin).” Confirm any User Account Control prompts.
2. Check if your system is in test mode by typing the following command and pressing Enter:

   bcdedit

   Look for a line that says “testsigning Yes.” If present, it indicates the test mode is enabled.

3. To disable test mode, type the following command and press Enter:

   bcdedit /set testsigning off

   This command instructs Windows to exit test signing mode.

4. Restart your computer to apply the change. You can do this by typing:

   shutdown /r /t 0

   or by clicking Restart in the Start menu.

5. After reboot, verify the change by opening Command Prompt again and typing

   bcdedit

   . The “testsigning” line should now read “No.”

6. If the watermark persists, double-check that the command was entered correctly and that your system has rebooted properly. If problems continue, consider running a system file check or Windows update.

Common Mistakes

• Not running Command Prompt as an administrator, which prevents commands from executing properly.
• Forgetting to restart the PC after executing the command, meaning the change won’t take effect.
• Entering incorrect commands or typos, which can cause errors or no change.
• Attempting to disable test mode with unsupported or third-party tools that may cause instability.
• Ignoring potential system issues that might be causing the watermark to stay, such as driver problems or system corruption.

Tips

• Always run Command Prompt or PowerShell as an administrator to ensure commands execute properly.
• Make sure to restart your computer after changing the test signing setting to see the effect.
• If you encounter errors, try running the System File Checker by typing

  sfc /scannow

  in an elevated command prompt.

• Keep your Windows 10 updated to avoid bugs that might interfere with the system’s normal operation.
• If the watermark remains after following these steps, consider resetting Windows or performing a repair install.

Troubleshooting

If the test mode watermark does not disappear after executing the commands and restarting your PC, follow these troubleshooting steps:

1. Re-verify the command: Open Command Prompt as administrator and run

   bcdedit

   again. Confirm that “testsigning” is set to “No.”

2. Check for pending Windows updates, as installing the latest updates can resolve bugs related to system settings.
3. Run the System File Checker to repair potential system corruption:

   sfc /scannow

4. Use the Deployment Image Servicing and Management (DISM) tool to repair the Windows image:

   DISM /Online /Cleanup-Image /RestoreHealth

5. If these steps do not work, consider resetting your system settings or performing a clean installation of Windows 10, after backing up your data.
