Where is application configuration information stored?



During the process of troubleshooting an application startup problem, you suspect that the issue is related to a problem in the application configuration. To fix the issue, you’ll need to directly modify the application configuration information in the operating system. Where does Windows store application configuration information?

A) The registry

B) The event log

C) The Windows explorer

D) The control panel


The answer: A) The registry

Windows consolidates all application and operating system configuration information into a large database called the Registry. For some application issues, modifying the registry is the only way to resolve the problem.

The incorrect answers:

B) The event log
The event log contains a record of any application problems, but it doesn’t store any application configuration information.

C) The Windows explorer
The Windows explorer is used to view files and folders in the operating system. The Windows explorer doesn’t store any application configuration details.

D) The control panel
The control panel is a great place to find operating system configuration information, but it doesn’t store any application configuration settings.
