Suddenly on the bottom right of my laptop screen appeared info like the image above which was quite disturbing to the view of the wallpaper used.

Quoting information from Microsoft , namely “The test mode message indicates that the test signing mode on the operating system starts on the computer. Test signing mode can be initiated if the program is installed in the testing phase because it uses a driver that is not digitally signed by Microsoft.

Microsoft is adding a test mode to Windows so that users can test programs without having to provide an authentication certificate.” But if I searched before, it seems that the drivers I use are official from each of the existing vendors, whether there is an automatic update to a certain party.

How to delete it is also very easy, currently I use the Windows 10 OS, but this method can also be applied in Windows 7 and Windows 8, only the difference is in the Command Prompt search, the commands used remain the same..

Here’s how to delete it:

  1. Click the Windows logo and then type cmd, then the search results will appear, right-click on the Command Prompt and then select Run as administrator, click Yes to continue if a warning window appears.

  1. Type “bcdedit -set TESTSIGNING OFF in the Command Prompt window that appears and then press Enter, if it has been successful, please restart Windows to see the result, very easy isn’t it.

Good luck and a great day.
