If it does mean that, then here's an answer:
Windows, actually should automatically update - when it is nescessery to patch, there will be an orange exclamation mark next to your shutdown button at the start menu. All you have to do is to shutdown, then turn on. Or restart. It should get updates while shutting down, and when it restarts is will apply those updates.
If you want to do it manually, then I guess:
Control Panel -> System and Security -> Windows Update
