Many PC users are faced with such a problem as test mode in Windows 10. Not everyone can turn off this annoying message hanging on the screen. But this guide will help you in this difficult matter. Here you will learn not only the main way to fix the problem, but also an additional one, more suitable for users who do not want to take risks.
Causes of the problem
Before you disable the test mode in Windows 10 Pro (or any other version of the "Tens"), you need to understand the causes of this malfunction. Most often this happens if:
- You manually disabled the driver digital signature control system.
- When installing any program, you agreed to activate the test mode.
- During the operation of the operating system, or during its next update, some kind of failure occurred.

In addition, the error often occurs when using a pirated Windows. In unlicensed versions, there may be several reasons for enabling test mode, ranging from driver signature verification, which is disabled by default, to modified system files. In general, you never know what the pirates “twisted” there.
Consequences
Even if you don't know how to disable test mode in Windows 10, there will be no serious consequences from this. The computer will continue to function normally. The only difference between the “test” operating system and the usual one is the corresponding inscription at the bottom of the desktop.
But if you still decide to take such a step as disabling the test mode in Windows 10, then you may have some trouble. The fact is that some programs and devices use unsigned drivers for their work. They, in turn, will cease to function normally after the test mode is deactivated, which may cause problems.
Main method
You can use the command line to disable test mode in Windows 10. This method is recommended by Microsoft, so it is considered the main one. To use it, do the following:
- Enter the command prompt.
- Type "bcdedit.exe" then hit space and add "-set TESTSIGNING OFF".
- Confirm changes and wait for the operation to complete.

Restart your PC. If you did everything correctly, the system will stop working in test mode and, accordingly, the inscription will disappear from the desktop.
Using a special program
Since disabling test mode in Windows 10 can sometimes lead to negative consequences, you can play it safe and use an alternative method. For this, the UWD utility will be used, which just serves to remove all kinds of inscriptions from the desktop. To use the app:
- Install the program and run it.
- Press the "Install" button, confirm the changes and wait for the operation to complete.
- The program will ask you to restart your PC. Do this and wait for your computer to turn on.

If you did everything right, the annoying inscription will disappear from your desktop. Please note that UWD does not disable the test mode, but only hides the message about its use.
