If you are like me that need to change the windows keyboard to input a foreign language like Japanese you may have experienced the situation where windows keep changing the default input language into something you don't want. Windows shouldn't change the keyboard layout automatically, but it remembers the individual language settings to every application as long as the application is running. To reset the input language to default, the application (process) must be ended and relaunched, or the input language manually changed.
I have researched this subject and have solved this problem by doing the following:
1. In "Region and Language" - tab-> Keyboards and languages->change keyboard->Default input language -> choose your language/country
Hope it helps.
