HKEY_CLASSES_ROOT. HKEY_CLASSES_ROOT or HKCR is an alias (i.e. a reference) to HKEY_LOCAL_MACHINE\Software\Classes. A separate root key is added mainly so software developers have direct access to this data without dipping in to HKLM. HKCR contains data related to applications, shortcuts, and file extension associations.
The 'c' means it's a character device. tty is a special file representing the 'controlling terminal' for the current process. Character Devices Unix supports 'device files', which aren't really files at all, but file-like access points to hardware devices. A 'character' device is one which is interfaced byte-by-byte (as opposed to buffered IO). TTY /dev/tty is a special file, representing the terminal for the current process.
