###Remarks###
A registry key must start with "HKEY_LOCAL_MACHINE" ("HKLM") or "HKEY_USERS" ("HKU") or "HKEY_CURRENT_USER" ("HKCU") or "HKEY_CLASSES_ROOT" ("HKCR") or "HKEY_CURRENT_CONFIG" ("HKCC").

When running on 64-bit Windows if you want to write a key or value specific to the 64-bit environment you have to suffix the HK... with 64 i.e. HKLM64.

AutoIt supports registry keys of type REG_BINARY, REG_SZ, REG_MULTI_SZ, REG_EXPAND_SZ, REG_QWORD, and REG_DWORD.

To access the <b>(Default)</b> value use <b>""</b> (a blank string) for the valuename.

When writing a REG_MULTI_SZ key you must separate each value with @LF.  The value must NOT end with @LF unless you want ant empty substring (see example).

It is possible to access remote registries by using a keyname in the form "\\computername\keyname".  To use this feature you must have the correct access rights on NT/2000/XP/2003.
