Use file signature verification to identify unsigned files on your computer and specify verification options.
These tasks are useful when determining whether to update a driver or when troubleshooting a problem you suspect is related to a driver.
To use file signature verification:
- Click Start, click Run, type sigverif in the Open box, and then click OK.
- Click Start to identify any files that are not signed. A list of files that have not been digitally signed appears.
- To set verification options, click Advanced. The Advanced File Signature Verification Settings dialog box appears.
You can choose to be notified if any system files are not signed, or you can search for files that are not digitally signed.
- To create, save, or view a log file, click the Logging tab.
The log file contains the results of the search. This log file can be archived and used during troubleshooting to compare driver settings from one point in time to
another point in time.
