ABC-Update is a free command line tool which allows you to take full control of Windows updates.

You can use it to list all your installed updates, for instance. To highlight any that are missing, or to find updates by their KB article number, release dates or category ("Application", "SecurityUpdates", "ServicePacks", more).

Of course the program can install your chosen updates, too. Or uninstall them. It's not particularly difficult. If you're the kind of person who might want to use this type of tool, then you'll immediately understand what a line like  ABC-Update.exe /A:Uninstall /K: KB2631813  is going to do, no need to go looking for help.

It's even possible to control Windows Update's normally automatic reboots. By default they're turned off, so  ABC-Update.exe /A:Install  will install all available updates without rebooting at all.

Or if you're downloading lots of updates, maybe onto a new PC, something like  ABC-Update.exe /A:Install /R:3  will set the total number of reboots you'll allow. Instead of waiting around as Windows Update restarts your system each time, ABC-Update will manage the process itself, installing as many updates as possible in each session, and only rebooting when absolutely necessary.

And there's more. Enter  ABC-Update.exe /?  at the command line to view everything the program has to offer.
