Windows 7 - Disable signature verification of drivers

Windows7 natively blocks unsigned drivers, preventing the installation of these drivers and making the device you want to install useless.

To get around this you must temporarily disable the signature verification process.

Solution

Disable signature verification of drivers:

• Go to Start Menu > Run and type the following command:

  • bcdedit /set nointegritychecks ON 

• Restart the PC and install the unsigned driver
• To enable back the signature verification, type the following command:
  

  • bcdedit /set nointegritychecks OFF

• Restart your PC
