Class Method Details

.check_key_exists(root_key, base_key) ⇒ Boolean

Checks if a key exists on the target registry

Parameters:

  • root_key (String) —

    the root part of the key path. Ex: HKEY_LOCAL_MACHINE

  • base_key (String) —

    the base part of the key path

Returns:

  • (Boolean) —

    true if the key exists on the target registry, false otherwise, even it the session hasn't permissions to access the target key.

Raises:
