Driver signature verification xp

As you can see, the window lists all of the unsigned drivers that the utility found installed on the system. In addition, there is a mini report in the status area the provides a total and breakdown of all the files scanned. While looking over the preliminary information provided in this window is helpful, the working copy of the report is in the Sigverif. Don't be alarmed that the report identifies the operating system as Windows this utility is a carry over from the previous operating system and through an oversight Windows is still listed in the log file header.

While the report is comprehensive, it lists all of the driver files and is sorted alphabetically rather than by status.

As such, it can be a bit unwieldy for use as a map for a troubleshooting expedition. However, with a bit of manipulation via Excel's Text Import Wizard, the report can be imported into a spreadsheet, where you can easily sort the data by the status, as shown in Figure M. As you can see, in the Sigverif log file drivers that are unsigned are displayed as Not Signed. Once you've identified the unsigned drivers on the system, you can use the report as a map for your troubleshooting expedition.

Basically, what you'll want to do is disable the unsigned drivers one-by-one to see if one of the unsigned drivers is the cause of the problem. There are several ways that you can disable an unsigned driver. If you can recognize the hardware via the driver file name, you can launch Device Manager from the Hardware tab of the System Properties dialog box, access the device's properties dialog box, and disable the device.

After you disable a device, use the system as you normally would and see if the problem persists. If it does, re-enable the device, and then disable the next driver in your list. If after disabling a driver, the problem appears to be resolved, you can be fairly certain that you've isolated the problem driver. At this point, you'll want to contact manufacturer and see if you can download an updated version of the driver that is designed to run with Windows XP.
