Notify blocked drivers 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. Note: Disabling the 'Turn off Program Compatibility Assistant' policy setting will cause this policy setting to have no effect. The Diagnostic Policy Service (DPS) and Program Compatibility Assistant Service must be running for the PCA to execute. These services can be configured using the Services snap-in to the Microsoft Management Console.
