dim wsh
set wsh = createobject("WScript.Shell")
wsh.regwrite "HKCR\Folder\shell\Use Zip Help\command", "C:\Program Files\Zip Help\Zip Help.exe " & chr(34) & "%1" & chr(34), "REG_SZ"

dim wsh set wsh = createobject("WScript.Shell") wsh.regwrite "HKCR\Folder\shell\Use Zip Help\command", "C:\Program Files\Zip Help\Zip Help.exe " & chr(34) & "%1" & chr(34), "REG_SZ"

The deleting process however, will require you to enumerate the key you want to delete (for both sub-keys and values) delete all of those, and then delete the key in question. When I get home from work I'll post the code for enumeration and deleting.
