Well get rid of them, you only need 1 language, right ?
You can remove updates by going into control panel>programs and features>view installed updates
then right click on an update to uninstall it.
Language Packs are not highlighted by default, you have to choose 1 to install it. So you probably didn`t. But you can always check.
You can rightclick each 1 in windows update and hide it so they don`t keep showing up.
