I failed to previously define the Windows NT Registry Data Types used in these tips.

 Data Type   D e s c r i p t i o n 
 REG_BINARY   
Raw binary data. Most hardware component information is stored as binary data. It can be displayed in Regedt32 as hexadecimal or binary.
 
 REG_DWORD   
A 4 byte (32 bit) number. It can be displayed in Regedt32 as binary, hexadecimal, or decimal.
 
 REG_EXPAND_SZ   
A text string that contains an environment variable that is replaced when retrieved. Example: %SystemRoot%\notepad.exe might be replaced with C:\WinNT\notepad.exe.
 
 REG_MULTI_SZ      
A list of multiple string entries, usually separated by nulls. The Multi_String Editor display each string on a separate line.
 
 REG_SZ   
A text string.
