Imaging Registry Settings (Windows CE 5.0)
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.
Note The default registry values vary depending on which Catalog items are included in your OS design. For more information, see Default Registry Settings.
Installed Codecs
The codecs that ship with Windows CE and appear in the Catalog are installed in the run-time image during the sysgen process. Their settings are not exposed in the registry.
If you want to install your own codec, you must create the following two registry subkeys:
- HKEY_CURRENT_USER\Software\Microsoft\Imaging\Codecs\<Codec Name>
- HKEY_LOCAL_MACHINE\Software\Microsoft\Imaging\Codecs\<Codec Name>.
The codec name that forms the last portion of these registry subkeys is the same value that is stored in the CodecName member of the ImageCodecInfo class.
Both subkeys use the same named values and each named value corresponds to a member of the ImageCodecInfo class. The following table shows the named values for these subkeys.
| Value : type | Description |

| CLSID : REG_BINARY | No default setting.
