How to Verify if System Files and Drivers are Digitally Signed in Windows

information   Information
To help maintain the integrity of your system, critical files have been digitally signed so that any changes to these files can be quickly detected.

Unsigned drivers donít necessarily have to be problematic or malicious, but it does make sense to check the system for those so you can uninstall them or find a updated signed driver.

This tutorial will show you how to check for and find any system files and drivers that are not digitally signed in Windows 7, Windows 8, and Windows 10.
