COM Registry Settings

The registry stores information necessary to configure the system for applications and hardware devices. The registry also contains information that the operating system continually references during operation.

To become functional, COM servers and containers must add information to the system registry. Most of that information is stored in keys and named values under the HKEY_LOCAL_MACHINE\SOFTWARE\Classes and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLE keys.

Note   HKEY_CLASSES_ROOT is equivalent to HKEY_LOCAL MACHINE\SOFTWARE\Classes and that these keys can be used interchangeably.

The named values associated with the HKEY_LOCAL_MACHINE\SOFTWARE\Classes registry key contain information about an application that is needed to support COM functionality.

For more information, see the following topics:

• (Non-Compound) FileType Key
• AppID Key
• CLSID Key
• Interface Key
• COM OEM Registry Settings
• OLE Key
• ProgID Key
• VersionIndependentProgID Key
