The Application Information (Appinfo) service facilitates running interactive applications with additional administrative privileges. If this service is stopped, users cannot start applications with the additional administrative privileges that they may require to perform certain user tasks. For example, if this service is disabled, system tools like Services and Regedit cannot run.

To enable this service after it has been disabled, you must start the computer in Safe Mode to get access to the Services snap-in console.

The default startup type for this service is Manual and it is started by applications that request additional privileges. When the Application Information service is started in its default configuration, it logs on by using the Local System account by default.

The Application Information service is dependent upon the following system components:

• Remote Procedure Call (RPC)
• DCOM Server Process Launcher
• RPC Endpoint Mapper
• User Profile Service
