Windows 7 natively blocks the installation of unsigned drivers, thus making the device/peripherals you want to connect to your computer useless.
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
Enable signature verification of drivers:
- Go to Start Menu > Run and type the following command:
-
bcdedit /set nointegritychecks OFF
-
- Restart your PC
