Windows cannot verify the digital signature of the driver required for this device. A software or hardware has recently changed and may have a signed or damaged file installed, or the file may be an unsolicited malicious software. (Code 52)

Recently replaced a new motherboard, upgraded WINDOWS10 RS2 (14955)

The good news is that Windows 10 is now like an apple, capable of supporting the coreaudio of those sound cards, and is free-drive.

The bad news is that you can't replace the manufacturer's own driver, only the official Microsoft driver. cannot be updated, and some features are certainly not.

My sound card is PreSonus Audiobox Ione, has always been required to install the driver, now do not have to Ann. But if you install the driver of the manufacturer, a line will appear at the beginning of the article. Unable to load driver, said to be a signature error.

So on the Internet to find how to ignore the problem of signature errors, found are Win7, no Win10. Press Win7 to try the following command line input:

Bcdedit.exe/set Nointegritychecks on

The result is useless and a hint appears: The value is protected by a secure boot policy and cannot be modified or deleted.

Do not know why, suddenly think of the motherboard BIOS option has a secure boot, so enter the motherboard BIOS settings, find the boot inside the secure boot, the Windows Uefi mode, switch to the other OS, and then the secure Key is deleted.

Save the settings and restart.

Start again, and sure enough the driver will load up.
