French/English Language conflict
I live in Canada. First language is English. My brother, who lives in France, visited last Fall. He brought a laptop while he was here with Win7 Pro installed on it (English Language). He used it via my ISP while he was here with no problems. He went back to France and, with no rhyme or reason, after some weeks, his laptop has completely converted overnight to the French Language - with no input from him. His ISP there is French of course, and I have to think that for some reason the conversion originated through the ISP servers. My brother is fluent in conversational French, but written French is not exactly his thing and he would prefer to read the laptop offerings in English.
One thing may be pertinent. He did a fairly big (30 minutes) Windows update just before this occurred.
How could this happen?
How can we switch this back to English and prevent it happening again?
Would a System Restore get us back to English?
