Deletes a subkey from the registry.
RegDeleteKey KeyName
Type: String
The full name of the registry key, e.g. "HKLM\Software\SomeApplication".
This must start with HKEY_LOCAL_MACHINE (or HKLM), HKEY_USERS (or HKU), HKEY_CURRENT_USER (or HKCU), HKEY_CLASSES_ROOT (or HKCR), or HKEY_CURRENT_CONFIG (or HKCC).
To access a remote registry, prepend the computer name and a backslash, e.g. "\\workstation01\HKLM".
KeyName can be omitted only if a registry loop is running, in which case it defaults to the key of the current loop item. If the item is a subkey, the full name of that subkey is used by default.
An OSError is thrown on failure.
A_LastError is set to the result of the operating system's GetLastError() function.
Warning: Deleting from the registry is potentially dangerous - please exercise caution!
To retrieve and operate upon multiple registry keys or values, consider using a registry loop.
Within a registry loop, RegDeleteKey does not necessarily delete the current loop item. If the item is a subkey, RegDeleteKey() deletes the key itself. If the item is a value, RegDeleteKey() deletes the key which contains that value, including all subkeys and values.
For details about how to access the registry of a remote computer, see the remarks in registry loop.
To delete entries from the 64-bit sections of the registry in a 32-bit script or vice versa, use SetRegView.
