Windows Explorer runs all those services you were missing. For some reason one time when you started your system Explorer must have crashed on loadup. When that happens it's supposed to automatically restart, but obviously didn't.

As usual a reboot won't ever tell you what went wrong but it will fix it.

Please note that the Windows 10 update process has been abnormally buggy and there's nothing you can do about it.
