Install an unsigned driver microsoft

Force the driver installation on Vista

Sometimes the installation of some drivers on Windows Vista blocks. When this happens, you can not run the device correctly.

Problem

Indeed, by default, Vista blocks unsigned drivers. We must disable the driver signature verification to install a driver recalcitrant.

Solution

To disable the driver signature verification:

  • To start, run and type:
      bcdedit / set nointegritychecks ON
  • Restart the PC and install the driver poses a problem.
  • Once the driver is installed, then protection is reactive:
  • To start, run and type:
      bcdedit / set nointegritychecks OFF
  • It reboots the PC one last time and that’s it
