Driver Signing Options In XP

Microsoft recommends that you only install drivers that have been tested for compatibility with Windows XP. Drivers that have met the Designed for Microsoft Windows XP logo requirements are digitally signed and safe to install on your computer.

Windows XP includes three different options for driver signing. The option you select will tell Windows what to do when it detects an unsigned driver (this is a driver that has not been tested with Windows). You can configure the driver signing options from the System Properties dialog box. Click the Hardware tab and then select the Driver Signing button. The three available options include:

• Ignore - Install the software anyway and don’t ask for my approval. Selecting this option means that any unsigned drivers will be installed on your computer and could cause instability.

• Warn - Prompt me each time to choose an action. If this option is selected, Windows will present a warning when you attempt to install an unsigned driver.
• Block - Never install unsigned driver software. By selecting this option, no unsigned drivers will be installed on the computer.
