To disable KMCS in Windows 7 64 bit, What is the difference between

  • bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
  • bcdedit.exe -set TESTSIGNING ON

Are both necessary or either one to load unsigned drivers?

Thanks for your help - Daniel

I believe support for DDISABLE_INTEGRITY_CHECKS to be completely removed (there are various windows updates that remove it). The only way to load unsigned drivers on Win7 64bit is if you enable test signing and leave it enabled for as long as you need the drivers.
