The Notify blocked drivers machine setting should be configured correctly. This policy setting determines whether the Program Compatibility Assistant (PCA) will diagnose drivers blocked due to compatibility issues. If you enable this policy setting, the PCA will notify the user of blocked driver issues with an option to check the Microsoft Web site for solutions. If you disable this policy setting, the PCA will not notify the user of blocked driver issues. Note: With this policy setting in a disabled state, the user will not be presented with solutions to blocked drivers. If you do not configure this policy setting, the PCA will notify the user of blocked driver issues with an option to check the Microsoft Web site for solutions.
