Legitimate Windows 7 users who are using the original and activated copies of Windows 7 versions are lately getting kind of weird “Test Mode Windows 7 Build 7600” watermark/message on the bottom right corner of their desktop just above the time zone area in the taskbar. This is really annoying as it appears suddenly anytime, users hardly knowing anything about the reason why it’s being showed up.
This message may appear when you follow one of the methods to disable driver signature checking in Windows 7. While implementing the method you may accidentally use the following commands
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
and these commands are found to cause this problem. Having known the cause of the problem, we just need to do the reverse (enable “Integrity_checks” and set “Testsigning” off). Let’s see the full solution to disable this message on your Windows.
Solution:
1. You need to first run the command prompt as an administrator before you could proceed to the next steps. Refer to this old post at Techrena to know how you can run the command prompt program as an administrator.
2. In the command prompt window type the following command
bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
and press enter and you must see “the operation completed successfully” message
now enter the following command and hit Enter again
bcdedit.exe -set TESTSIGNING OFF
and again you should get the same above success message. Refer to the screenshots posted below:
3. Reboot your Windows and see the changes, the “Test Mode Windows 7 Build 7600” watermark disappears. That’s all.
