SYMPTOMS
On a computer that is running Windows Vista, when you use the Reg.exe tool to query a registry subkey, you may receive the following error message:

ERROR: More data is available.

This problem occurs if the registry subkey contains null-terminate registry entries. These registry entries have some non-standard letters. Although these registry entries appear to be correct, their binary data does not reflect a correct value.



CAUSE
The issue occurs because the Reg.exe tool does not allocate sufficient buffer for the registry subkey that contains null-terminate registry entries.
