a) Install updates automatically. Windows will regularly check for new updates and apply them automatically (this is the recommended option).

as they appear (if they apply to your system).

By default, the 'Automatic Updates' service will find and download updates for you. If you cannot wait then there are a number of commands and scripts you can use:

a) Run Wuauclt /detectnow to force Windows to look for any new updates from Microsoft or WSUS server.
b) Run the cscript WUA_SearchDownloadInstall.vbs script to find and install any new updates.
c) You can download and install using the WSUSOffline tool which has a useful GUI to download/install updates and create ISOs so that it can be used on multiple machines.
