More Information

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.
