WriteRegDWORD
root_key subkey key_name value
This command writes a dword (32 bit integer) to the registry (a user variable can be specified). Valid values for root_key are listed under WriteRegStr. The error flag is set if the dword could not be written to the registry. If the registry key doesn't exist it will be created.
