Windows 7: Trouble with language settings. STUCK!

Sigh...very frustrating..

I have a dual language set-up going on my laptop of English as the primary and Korean as an option. For some reason, my computer shut down on its own for whatever reason, then upon start-up and log-in, the language settings were automatically changed to Korean. Unfortunately, I'm not fluent in it, so I don't know how to go about changing it back to English.
On a side-note, after this happened, there was an indication of an update on my Shut Down button, which I clicked and updated. During the update installation process, on the bottom of the screen was the usual Windows 7 logo, but had a Red-Orange "K" after it. Dunno what that was (gonna take a wild guess and say "Korean"?), but it went away..



Anyway, main problem is the language setting, which, for the record, happens often with Windows, in my experience. Anyone able to assist?

Scratch that. I got it. Went to the Start Menu, searched "Regional and Language Settings" and hit Enter so I wouldn't have to navigate aimlessly and changed it back. Dunno why the f*** it was changed in the first place though..!

alt+shift works for me

The red/orange K could also have been Kaspersky (if you have that on your system).
