In Chapter 9, you learned that digitally unsigned drivers are often the cause of system instabilities. To ensure you don’t accumulate unsigned drivers on your system (particularly if you share your computer with other users), you should regularly run the Signature Verification Tool. This program scans your entire system (or, optionally, a specific folder) for unsigned drivers. Follow these steps to run this tool:
Select Start, Run, enter sigverif, and click OK. The File Signature Verification window appears.
Click Advanced to display the Advanced File Signature Verification Settings dialog box.
Select the Look For Other Files That Are Not Digitally Signed option.
In the Look In This Folder text box, enter SystemRootSystem32drivers, where SystemRoot is the folder in which Windows XP is installed (such as C:WINDOWS).
Click OK.
Click Start to begin the verification process.
When the verification is complete, the program displays a list of the unsigned driver files. (The results for all the scanned files are copied to the log file Sigverif.txt, which is located in the %SystemRoot% folder. In the Status column, look for files listed as "Not Signed.")
