    CMD crashes when running "bcdedit -set TESTSIGNING ON"


    To get the driver for an old audio interface to install, I have to run a script which includes the line "bcdedit -set TESTSIGNING ON" so that Windows will accept a modified inf file. This has worked fine on two other machines running Windows 10, but on my new laptop this command makes the CMD window crash without turning test signing on. Is there a way to fix this?

    I tried it, but it still crashes. I'd be surprised if the syntax was the problem now because the same command worked in the past.

    Thanks for the suggestions. Unfortunately neither scannow nor dism can see any problems.

    I tried running the command in the other direction, to turn test signing off, and it didn't crash, but it also told me that I wasn't allowed to do it. I can't remember the exact message now, but it was something to do with locking down the boot process. This machine is new hardware with the OS installed by the manufacturer. I had previously installed the driver on older hardware with the OS installed from a disk. I suspect the difference lies somewhere there and I have more or less accepted that what I wanted to do is not possible.

    You could try turning off secure boot in BIOS. That blocks testsigning.

    Did you turn off secure boot in BIOS?
