need help with enabling and disabling signed driver enforcement in vista 64

[poopy]

OK, I have come across 3 methods to disable driver signing with the bcdedit program on various websites:
bcdedit.exe /set testsigning on/off
bcdedit.exe /set nointegritychecks on/off
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

What are the differences between them and which one should I use? Oh, how do you re-enable driver signing for the DDISABLE_INTEGRITY_CHECKS method, if I use it?

I'm using the last one and to re-enable it type: bcdedit /deletevalue loadoptions

I disabled User Account Control (UAC) and it disapeared for me
