CurrentControlSet is then “pointed” at CurrentControlSet001, to which it serves as a shortcut. When your computer first starts up, Windows copies HKLM\SYSTEM\ CurrentControlSet to HKLM\SYSTEM\ Clone. In reality, CurrentControlSet is actually a shortcut/pointer to one of CurrentControlSet001, CurrentControlSet002, or Clone. To protect against system errors and provide an easy recovery option, each time Windows is successfully booted, the old CurrentControlSet and all its contents is copied and set aside.
