Well thank you to everyone for the input. I too like Richard have unknown input data which seems to indicate that unless I can track this down and come up with some work around I won't be able to actually edit the entries as I had wanted to because KiX won't be able to write back that type of data natively.

Of note Bryce has previously written a couple UDFs to attempt to deal with such Registry data and are located here
RegHEXtoASCII
RegASCIItoHEX
