When you are trying to install a driver, if you get warning message “Windows requires a digitally signed driver“, it means the driver is unsigned. There’re two methods to install the driver successfully. Just pick up the method you like.
Method 1: Disable the driver signing in Windows
It is not recommended you install unsigned driver or application. But if you got the driver from official manufacturer’s website, you can install it anyway, which will guarantee the safety. To install the driver, you need to disable the driver signing in Windows.
IMPORTANT: Ensure you get the driver from official manufacturer’s website. If you get this error when trying to install the driver from the third party, it may cause problems.
Follow these steps to disable the driver signing.
1) Press Win+R (Windows key and R key) at the same time. A Run dialog box will appear.
2) Type gpedit.msc in the run box and click OK button.
3) Click User Configuration in left pane and double-click on Administrative Templates in the right pane.
4) Double-click on System.
5) Double-click on Driver Installation.
6) Double-click on Code signing for device drivers.
7) Select Enabled change it to Ignore from the drop-down menu. Then click OK button.
After disabling the code signing for device drivers, install the driver and it should work this time.
IMPORTANT: Remember to enable the code signing for device drivers after installing the driver, as this will prevent your computer from installing any unsigned application or driver without any warning.
