If you start your Windows 11 PC and notice a “Test Mode” watermark in the lower-right corner of your desktop, do not worry as it can be removed easily. This watermark indicates that Windows has disabled both device driver integrity checks and digital signature enforcement.
Why Does Test Mode Appear?
Test Mode is a special Windows state that allows users to load and install unsigned or non-certified device drivers. It is primarily used by developers to test new drivers before they are officially signed and released. While this mode is beneficial for testing purposes, having it enabled on a regular system can pose security risks, as it allows potentially unverified software to run.
How to Remove the Test Mode Watermark
To disable Test Mode and remove the watermark from your Windows 11 desktop (these steps also apply to Windows 10), follow these instructions:
Step 1: Open Command Prompt as Administrator
- Click on the Start button.
- Type cmd in the search bar.
- Right-click on Command Prompt (cmd.exe) and select Run as administrator.
Step 2: Run the Necessary Commands
In the elevated command prompt window, type or copy-paste the following commands one by one, pressing Enter after each:
Bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS Bcdedit.exe -set TESTSIGNING OFF
These commands will re-enable Windows driver integrity checks and disable the Test Mode setting.
Step 3: Restart Your Computer
Once you have entered the commands, restart your PC. After rebooting, the Test Mode watermark should be gone.
Alternative Method: Using the Advanced Boot Menu
If the command prompt method does not work, you can try disabling Test Mode using the Advanced Startup Options in the following manner:
- Click on Start, then click on power icon, hold down Shift key on keyboard while clicking Restart. This will restart your Windows PC into Advanced Startup screen.
- In the Advanced Startup Menu select Troubleshoot, then Advanced Options, and then Startup Settings.
- Choose Disable Driver Signature Enforcement and click Restart.
- Once booted, repeat the command prompt method above to disable Test Mode permanently.
Conclusion
Test Mode in Windows is a useful feature for developers, but for regular users, it can be unnecessary and even pose a security risk. By following the steps above, you can easily remove the Test Mode watermark and ensure that your system enforces driver signature verification.
