@REGBWRITE[HKEY...\subkey\value,type,handle,length]: Write a value from a binary buffer to the registry.
type : The type of key. @REGBWRITE supports keys of type REG_BINARY and REG_NONE.
handle : A buffer previously created with @BALLOC.
length : The length (in bytes) to write to the registry key.
If @REGBWRITE succeeds, it returns "0", otherwise it returns the Windows error number.
If you are running a 64-bit version of Windows, you can access the 64-bit registry instead of the 32-bit registry by appending "_64" to the HKEY name.
If the key name begins with \\machinename, @REGBWRITE opens the registry on a remote machine. The remote registry service must be running on the remote machine, and you must have access and permissions. The HKEY parameter can be one of the following keys:
HKEY_CLASSES_ROOT (or HKCR)
HKEY_CURRENT_CONFIG (or HKCC)
HKEY_CURRENT_USER (or HKCU)
HKEY_LOCAL_MACHINE (or HKLM)
HKEY_PERFORMANCE_DATA (or HKPD)
HKEY_USERS (or HKU)
Note: Remember to use quotes around any entry containing spaces or commas!
