Some users experience a “Test Mode” message appearing in the lower right corner of the screen. There are two ways to get rid of it: simply hide the inscription or actually disable the test mode.
Why does the inscription appear?
Typically, a notification appears on the screen after checking is disabled digital signature drivers. The scan can be disabled manually by the user or deactivated in the build if an unofficial version of Windows 10 is installed. 
The easiest way to get rid of the message in the corner of the screen is to disable test mode using the command line. But this can be fraught with errors in the operation of equipment and programs that use unsigned drivers. Therefore, if after disabling the system begins to malfunction, you should start the mode back and remove only the watermark itself.
Shutdown
To disable, run Command Prompt with administrative privileges.
If the command does not work, then restart the computer, go into the BIOS and disable Secure Boot.
If, after disabling test mode, problems arise in the operation of programs or hardware, activate it back using the command “bcdedit.exe -set TESTSIGNING ON”.
Removing a caption
If you can’t disable the mode, then simply remove the inscription in the corner of the desktop so that it does not block the usable space. You can use several to achieve your goal free programs. One of the tested utilities is called Universal Watermark Disabler. You can get rid of the inscription using it in three steps:
After restarting the system, you will not see the watermark in the corner, which is located on top of all windows. But in fact, the system will continue to work in test mode unless you disable it via the command line.
Test mode has always been a problem operating system Windows, and it has not disappeared anywhere in Windows 10. By installing unsigned drivers on the computer, the user runs the risk of encountering a situation where in the lower right corner of the screen he sees the inscription “Test mode”, followed by accurate name operating system and build version. This will not reduce the functionality of Windows, but this inscription on the screen will take up space, which is not suitable for all users. In this article, we will consider: how to enable/disable test mode in Windows 10 or simply remove the inscription.
What is Windows 10 Test Mode
Thousands of applications are developed for the Windows operating system, each of which must be compatible with different computers. They differ not only in hardware, but also in the versions of installed operating systems. To test an application or, for example, an unsigned driver, the user can activate test mode in Windows 10. On versions of the 64-bit operating system, test mode also allows you to remove some security restrictions.
Activating test mode in the Windows 10 operating system is quite simple; to do this, you need to do the following:
- Run command line as administrator;
- Enter the command in it: bcdedit.exe -set TESTSIGNING ON
- Press Enter.
After such simple manipulations, the test mode will be activated.
How to disable test mode in Windows 10
There may be situations where Windows 10 test mode activates spontaneously. In such cases, it is better for the user to disable it as soon as possible, since in test mode the system is more vulnerable from a security point of view. Test mode is also disabled in Windows 10 through the command line launched as an administrator. You need to enter the following command in it:
Bcdedit.exe -set TESTSIGNING OFF
After entering the command, press Enter and restart your computer.
If this method did not help correct the situation and after rebooting the computer the test mode remained activated, you will need to do the following:
Note: The methods described above for enabling and disabling test mode in Windows 10 are also relevant for previous versions of the operating system - Windows 7, Windows 8, Windows 8.1.
How to hide the “Test Mode” label in Windows 10
The above described ways to disable test mode in Windows 10. But some users, for one reason or another, have to use it constantly, and they may just need to hide the text indicating test mode, which is located in the lower right corner of the screen.
In the operating system settings, as well as using system utilities, you won’t be able to hide information about the Windows 10 test mode. In order for the mode to remain activated, but the inscription disappears, you will need to apply third party solution. The most popular application that allows you to hide the Windows 10 test mode message is Universal Watermark Disabler. This program can be downloaded from the official website of the developers, where it is distributed free of charge.
After downloading the Universal Watermark Disabler application, launch it and click Install.
After this, the application will display a message (in most cases) that its operation on the current build of Windows has not been tested. Click Yes.
After this, the inscription in the lower right corner of the screen that Windows 10 is running in test mode will disappear, while the system will continue to operate in test mode. If you need to disable it in the future, you can do this using the method described above.
While working on a computer, situations sometimes arise (for example, when connecting Android devices to flash them) when you need to install specific and unsigned hardware drivers. In this case, it is best to use Windows test mode. Let's consider this issue in more detail.
Enable test mode in the Windows command line
In order for the transition to test mode to be successful, you must first disable the “Secure Boot” mode in the BIOS, so before starting you need to log into your computer. For various manufacturers motherboards the settings will be slightly different, but we will figure out how to disable “Secure Boot” using the example of a computer we have with motherboard Asus.
So: launch the BIOS (UEFI) and go to the “Boot” section. In it, go to the “Secure Boot” item and click on it.
A small “OS Type” menu appears, in which we select the “Other OS” item.
We save the parameters and reboot. If there is no “Secure Boot” item in your BIOS menu, then it is already disabled at the hardware level and there is no need to perform the above steps.
Now you can run the “ten” in test mode to remove some OS restrictions, in particular those that are imposed when installing unsigned drivers. Launch (with administrator rights), enter the command:
bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit . exe — set TESTSIGNING ON
We wait for the completion of each command, after which the system will issue a corresponding notification.
Close the window and reboot. After the reboot, next to the notification panel we will see an inscription reminding you of the mode in which the operating system is now running.
You can disable test mode in a similar way, only the command syntax will be slightly different:
bcdedit . exe — set TESTSIGNING OFF
If the command gives an error, turn off Secure Boot mode in the BIOS.
P.S.
Performing actions in command line, be careful. And remember - Windows work 10 in test mode reduces the security of the operating system significantly.
Test mode in Windows 10, as well as in others windows versions, may turn on automatically when installing unsigned drivers. But sometimes the user needs to enable it himself in order to install such drivers for the operation of homemade peripherals, for testing, etc. This is especially true on 64-bit systems with increased security, because it allows you to remove some restrictions.
How to disable test mode?
To disable it, one command is usually enough.
- Go to the menu Start -> All Applications -> System Tools - Windows -> Command Prompt(by right-clicking on it - run as administrator )
- A black console will start, enter the command bcdedit.exe -set TESTSIGNING OFF into it
- Press “Enter”, then restart the computer.
If you did everything correctly, the “Test mode” sign will disappear.
But it happens that one command is not enough, and the inscription remains after a reboot. Then you need to do the following:
- We repeat point one from the previous list
- Enter the command bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
- Press “Enter”
- Enter the command bcdedit.exe -set TESTSIGNING OFF
- Press “Enter”
- Let's reboot.
Voila! The inscription is gone! Test mode disabled!
How to enable test mode?
Test mode is turned on with the command bcdedit.exe -set TESTSIGNING ON and that’s it! Reboot!
Finally, I want to say that this method is also valid for Windows 7, Windows 8, and Windows 8.1
That's all, good luck to you!
