How to close the Xiaomi notebook system "test mode" in Win10

  
Xiaomi notebook Air 13, this computer's out of the box has been released, but after the first boot, it found that there is a watermark in the lower right corner of the screen, is Win10 "test mode". This mode disables the driver mandatory signature mode, which is used to turn off system driver signatures and install drivers and programs that are not signed. As for why this computer defaults to this mode when it is turned on, it is not easy to say, and it is not certain whether this is a common phenomenon.

However, it is difficult to log in to the Microsoft account in this mode (the test machine defaults to the local account with the user name "MI”, the test mode is difficult to use the next "IT Home" app), login interface Will crash and crash. I wasn't sure about the test pattern at first, but the watermark was suspicious, so I tried to close it.
The method is very simple, run the command prompt in the administrator mode, a command will be done:
bcdedit /set testsigning off

After pressing Enter, the system will prompt “success” However, the watermark will not disappear immediately, you need to restart the computer, the logout is invalid. After the restart, not only the watermark disappeared, but also the problem of logging in to the Microsoft account was solved. The APP such as "IT House" can be downloaded normally.

If you need to enter the "test mode", you can also run the command prompt in the administrator mode, execute the following command:
bcdedit /set testsigning on
is also effective after restart .
