Level 2 blocks installation of a driver that fails the signature check. The user is notified that the driver cannot be installed because it is not digitally signed. You can start the Signature Checking feature by using the Hardware tab of the System Properties dialog box. You can use this tool to identify a driver that might be causing problems due to corruption or because it is missing, not loaded, or outdated. Run Drivers from a command prompt, rather than from Windows Explorer, to see the resulting display.
Drivers has no command-line switches.
Tip Run Drivers when the system is working properly and save the output to a file. You can use these results as a comparison later if the system has problems with missing or corrupted drivers. Keep this file in a safe location or print it and record the date on the page. Table 31.12 describes the output from the Drivers tool. The most important field is Module Name , which is the name of the component.
