For windows vista, auto update won't work anymore. You will need to go to the Microsoft update site where they list older updates and select it from a list.

Sorry, but that's not correct. Windows Update does still work and actually still works all the way back to Windows 98 (the first version that including a method of Windows Update). Obviously those earlier operating systems are now unsupported and there haven't been any new patches for a long time, but all the original updates are still there for download, if needed.

With Windows Vista and newer you don't need to visit the website as it's more integrated into the operating system, but it still uses the same technology which is all still online/functional.
