Windows magically adds languages to my keyboard layout list

Two new keyboards have somehow appeared in my keyboard layout list:

The bottom two (German, and English - United Kingdom) are emphatically not in my system language list, so I cannot remove them!

I was browsing the Inteet for the past few hours, so could it be caused by Chrome? (E.g. when typing text in a textbox with lang=de, it could have somehow added a German keyboard for me). If so, how can I disable this, and prevent other programs from doing the same in the future?

Also, how do I remove those layouts now? The problem might go away if I log off and on again, but I'd prefer not to have to do it every time.
