Why dont you just try moveing the batch file then deleteing the registery.
:oI dont have the REANME command fresse in my head, so please excess the fact the ive told you the wrong command parameters.
Example:
rename BATCH.bat -a "C:\OtherFolder"
delete "C:\OrginalFolder"
Maybe?
I'm really not sure... i dont know a whole lot about batch files. But, excessing the wrong commands, that would work (if i am understanding you)
