How to Verify if System Files and Drivers are Digitally Signed in Windows
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 don’t 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.
File Signature Verification (sigverif.exe) saves its results to the log file below.
C:\Users\Public\Documents\SIGVERIF.TXT
Here's How:
1 Press the Win + R keys to open Run, type sigverif into Run, and click/tap on OK to open "File Signature Verification".
2 Click/tap on Start. (see screenshot below)
If you like, you can click/tap on Advanced first to change the logging settings to what you want instead of the default settings, and click/tap on OK to apply.
3 File Signature Verification will now scan your system files and drivers. (see screenshot below)
4 When finished, all unsigned system files and drivers are displayed in the results with its file name, full folder path, modified, file type, and version details. (see screenshot below)
Depending on the results, you may want to keep the file(s), search for an updated version of it, or remove it from being started with Windows.
That's it,
