How to install updates, but without shutdown?

[quadboi]

Hi, I want to install updates, but select the ones to install. Not install them all in one go on shutdown, how can I do this ?

It has downloaded them all I believe, hence saying it wants to install them on shutdown.... please help. In need!

Thanks

Also theres no "windows update" icon in my tray...
