PyCharm changes system keyboard layout

Question

I'm using PyCharm Community Edition 2016.3 Build #PC-163.8233.8 on Windows 10, and it erratically changes the system-wide keyboard layout from German to English. I want it to stop doing that but haven't found any setting related to this.

My problem seems to be related but different from this question, where the internal PyCharm setting is set to German for some reason.

Answer 1

It turns out this is related to Windows 10, not PyCharm. In PyCharm, one often uses Alt + Shift + E to execute code. In Windows 10, Alt + Shift (sometimes Ctrl + Shift) also switches keyboard layouts, so this explains the behavior. Following this answer, one can change this at Control Panel\Clock, Language, and Region\Language\Advanced settings under "Change language bar hot keys".
