I would be very careful about removing any Windows files at all. The files you mention take up such insignificant space.
Removing windows files can often lead to an OS re-install.

The best thing you can do to keep your PC running smoothly and sharp is to give it a good clean -up using Disk clean-up and leave windows alone to manage itself. A job it does far better than any user.

See Using Disk Cleanup.
