Windows 10: Test Mode Text Appears after a few hours

About 2 hours after starting up my computer and after restarting a big Test Mode text appears over my screen. I've tried the stated solution of using the command prompt to get rid of it, but get "The value is protected by Secure Boot policy and cannot be modified or deleted" back. I haven't done any modifications to my system, and didn't download anything before this happened, so I have no idea what could be causing this.

Test Mode Watermark Windows 10

Hi Lee,

To assist you better, kindly provide us more details by answering the following questions:

• Which operating system are you using?
  
• When did you start encountering the issue?
  
• Have you made any changes on your computer prior to the issue?

The test mode message indicates that the test signing mode of the operating system is started on the computer. The test signing mode may start if an installed program is in a test phase because it uses drivers that are not digitally signed by Microsoft.
Microsoft added test mode to Windows so that users can test programs without having to provide an authentication certificate.

Meanwhile, to help resolve your concern, we suggest that you follow the steps below:

• Press Windows key + X on your keyboard.
  
• Choose Command Prompt (Admin).
  
• Copy or type the command below and then hit Enter:
  
  bcdedit -set TESTSIGNING OFF

Should you need further assistance, feel free to get back to us.

 

Test Sign mode

Hi Koutz,

The test mode message indicates that the test signing mode of the operating system is started on the computer. The test signing mode may start if an installed program is in a test phase because it uses drivers that are not digitally signed by Microsoft.

I'd like to know some details of the concern to help provide the appropriate resolution. Kindly answer the following question below:

• Which build and version of Windows 10 are you running?
• Is BitLocker enabled on your computer?

For you to disable the test mode, you will need to run it as an administrator. To do this:

• Search cmd on the taskbar then right-click on
  Command Prompt then select Run as administrator.
  If you are prompted by a User Account Control window, tap or click Yes.
  
• In the Command Prompt window, type the following command, and then press Enter:bcdedit -set TESTSIGNING OFF
  
• After you see the confirmation, close the Command Prompt window.
• Save any unsaved work, and then restart the computer.

If it still wouldn't disable the test mode, I suggest that you enable the built-in administrator account so you can disable this feature. Please note that you will be using this solely for troubleshooting purposes only. I do recommend disabling this after
the troubleshooting to avoid messing up your computer's functionality.

To enable the built-in administrator account, follow these steps:

• Type cmd in the search bar, right-click Command Prompt, and then click
  Run as Administrator.
• When you are prompted by User Account Control, click Continue.
  
• At the command prompt, type net user administrator /active:yes, and then press Enter.
• Type net user administrator <Password>, and then press Enter.
  
  Note In this command, <Password> represents the actual password that you want to set for the administrator account.
• Type exit, and then press Enter.
• Log off the current user account.
• Log back in with the admin account then disable the test mode by following the steps above or you can refer to this
  link.

To disable the built-in administrator account, follow these steps:

• Type cmd in the search bar, right-click
  Command Prompt, and then click Run as Administrator.
• When you are prompted by User Account Control, click Continue.
  
• At the command prompt, type net user administrator /active:no, and then press Enter.
• Type exit, and then press Enter.
• Log off the current user account.

Update us with the results.
