I understand that you want to delete those files which were not uninstalled completely from the laptop by deleting the registry keys but, I suggest you not the delete the registry keys as it might cause serious problems.
The Wow6432Node registry entry indicates that you are running a 64-bit Windows version.
The operating system uses this key to display a separate view of HKEY_LOCAL_MACHINE\SOFTWARE for 32-bit applications that run on 64-bit Windows versions. When a 32-bit application writes or reads a value under the HKEY_LOCAL_MACHINE\SOFTWARE<company><product> subkey, the application reads from the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node<company><product> subkey.
