For those having issues install drivers on Windows 8...

I was struggling with getting the drivers for my Galaxy Nexus Fastboot protocol installed on Windows 8. On Windows 7, the supplied CAT files worked fine with a manual install. On Windows 8, I was getting "hash check" errors. Very frustrating.

Luckily, I figured out how to turn off these driver verification checks.

In order to do this, you must enter the following commands in command prompt (run as administrator)

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

then reboot.

Please keep in mind that this MAKES YOU VULNERABLE to malicious drivers, packages, blah, blah, blah.

Once you've installed the drivers you've been having trouble with, you can turn it off with these commands using the same process.

bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING OFF

Worked great for my proprietary SSL VPN software as well as Android drivers.

Howdy, just created an account so I could comment on this: THANK YOU! I spent 8 hours yesterday trying to install Android drivers so I could flash my phone, beyond frustrating! Finally found this post, punched in the commands (honestly a bit above my pay-grade), and was able to get everything working. A lifesaver! I know this is 3.5 years old, but still works for driver installation issues on Windows 10.1. Again, cheers, and thank you. Don't forget to turn off once you're done!

This is the same process I had to go through in order to install the drivers for my 3D Printers last year.

I understand Microsoft's desire to ensure malware infected drivers are not installed. I also recognize that the manufacturers of 3D Printers aren't necessarily in lock-step with Microsoft.

But, Microsoft should create a better method to get drivers approved or added to the Hardware Compatibility List so one doesn't have to jump through flaming hoops of death just to install the drivers for a peripheral.

I'm glad 2012 me was able to help 2016 you out. Hopefully 2016 me can still be helpful in the future.

You can create your own signing key and sign your own drivers.
