Fix Unsigned Driver issue with older hardware Windows 10

1. Change the Startup settings

This is the simplest way to disable driver signature enforcement on Windows 10 but bear in mind that this method will only disable driver signature temporarily.

After you restart your computer driver signature enforcement will automatically turn itself on.

To disable driver signature enforcement do the following:

1. Press and hold the Shift key on your keyboard and click the Restart button.
   
2. Choose Troubleshoot > Advanced options > Startup Settings and click the Restart button.
3. When your computer restarts you’ll see a list of options. Press F7 on your keyboard to select Disable driver signature enforcement.
4. Your computer will now restart and you’ll be able to install unsigned drivers.

Bear in mind that this method only temporarily disables driver signature enforcement, so be sure to install all the unsigned drivers as soon as you can.

You can automatically install the drivers you need by using dedicated software that installs all of your out-of-date and missing drivers for you.
