The Loaders registry subkey contains a subkey for each Guide database loader installed. The name of the subkey for a loader is the loader's globally unique identifier (GUID). The Loaders subkey is as follows:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TV
     Services\Guide\Loaders\LoaderGUIDs
LoaderGUIDs is a list of the GUIDs for all loaders. The following table describes the values under each subkey identified by a loader GUID.
| Value name | Data type | Meaning | 
|---|---|---|
| Name | String | File name of the DLL for the specified loader. | 
| TuningID | Binary | Pointer to the tuning spaces handled by the specified loader. | 
| LastAttemptTime | Binary | Date and time the specified loader most recently started. If this entry does not exist, then the loader never attempted to run. | 
| LastCompletionTime | Binary | Date and time the specified loader most recently finished running. If this entry does not exist, then the loader never finished running successfully. | 
| LastCompletionResult | DWORD | Return value from the DLL for the specified loader the last time it finished running. | 
Each loader can have additional loader-specific information in the Loaders subkey.
