Remove “Test Mode” from desktop of Windows 8.1


Windows 8.1 released today.  I’ve been using it since they released it to Technet and MSDN subscribers last month.  It’s had an annoying “Test Mode Windows 8.1 Pro Build 9600″ message on the desktop since I installed it.  I finally took time today to find out how to get rid of it.

Launch a command prompt as Administrator.

Type:  bcdedit -set TESTSIGNING OFF


No more Test Mode message.


Update (10/20/2013):  I’ve had one commenter say this doesn’t work for non-Pro versions of Windows 8.1.  I haven’t verified this.


  1. Sorry, does not work in non-Pro version!
    Also I have a warning about “secure boot”

  2. Does this just hide the message, or does it turn off non-signed driver support? I’m guessing the latter… :/

  3. My guess would be that it just hides the message.

  4. Tried it out; it disables non-signed drivers. Not what I need.

  5. Doesn’t work for Windows 8.1 Enterprise

  6. This works. Windows 8.1 Pro. Lots of thanks!!
