Default Behavior

Application Information is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Application Information service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If Application Information fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the Appinfo service hasn't been started.

Dependencies

Application Information can't start, if any service from the list below is disabled or not available:

Restore Default Startup Configuration for Application Information

Before you begin doing this, make sure that all the services on which Application Information depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config Appinfo start= demand

3. Close the command window and restart the computer.

The Appinfo service is using the appinfo.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
