I purchased a Surface Pro 2 in the US and then moved to Spain. I just completed a warranty exchange here in Spain and received a Spanish version SP2.
I immediately changed the display language to English and almost all of the system is using the English language. The only time I'm seeing Spanish is when the system displays certain messages.
For example, when I restarted so updates could be installed, I see the message:
"Instalando actualizacion 25 de 40...No apague el equipo."
I can't figure out how to change those messages to English. Any help is appreciated!
