Is there a way to forever disable driver signature enforcement in Windows 8?

I keep seeing this solution posted on various blogs and forums:

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

but it is not working, at least not like when you manually disable driver signature enforcement.

To disable driver signature enforcement, I currently have to do this everytime I restart my PC:

1. From the Metro Start Screen, open Settings (move your mouse to the bottom-right-corner of the screen and wait for the pop-out bar to appear, then click the Gear icon).
2. Click ‘More PC Settings’.
3. Click ‘General’.
4. Scroll down, and click ‘Restart now’ under ‘Advanced startup’.
5. Click ‘Troubleshoot’.
6. Click ‘Advanced Options’
7. Click ‘Windows Startup Settings’
8. Click Restart.

Is there at least a way to create a shortcut or something? F8, Shift+F8 don't work any more at boot. These MS developers freaks really want everything their way only.

What's worse is that when I have to power up my PC, I first have to start normally and then restart with driver signature enforcement disabled, because there is no way to tell Windows 8 to show the troubleshoot screen when a PC is powered up.
