Question

which of the following registry keys might contain information that a vm is installed on a computer?
o a. hfile_classes_root
o b. hkey_classes_root
o c. hfile_extensions
o d. hkey_classes_file

Explanation:

HKEY_CLASSES_ROOT is a valid Windows Registry hive that stores file association and component object model data, including entries related to virtual machine software installations. The other options are invalid or non-standard Registry key names: HFILE_CLASSES_ROOT, HFILE_EXTENSIONS, and HKEY_CLASSES_FILE do not correspond to actual Windows Registry hives relevant for VM installation data.

Answer:

b. HKEY_CLASSES_ROOT
