Removing the Test Mode Watermark From the Windows 10 Desktop
概要: The Windows 10 Test mode message may present itself in one of two different ways. See the section that matches what is on your computer.
手順
Are you looking to remove the test mode messaging from the Windows 10 desktop on your personal computer?
There is a function of Windows 10 called Test Mode which allows you to install and test drivers that have not been digitally signed through Microsoft. This mode as the name indicates helps test software or drivers that are still being developed or have not been certified yet. If you start up your personal computer and a message or watermark is visible saying Test Mode or Testing Mode, that indicates that the mode has been activated and is running on your personal computer.
The most common reason for this is the installation of some drivers that are still in their testing phase. You will see either a message in the lower left corner or a full-screen message in gray.
