I had similar issues with Hotmail more than five years ago , albeit none right now. I happened to set the default language/Locale to Simplified Chinese for once, and changed it back to English shortly afterwards. Somehow Hotmail insisted on showing everything in Chinese, its email interface, service agreement etc. So I had to go to the settings and changed it every now and then. Anyway I slowly drifted to using Linux desktop full time on my machine, and the issue disappeared magically.
