Per app input language Windows 10

Solution 1:

In my "Windows 10 Pro" "Version 1809" is not this settings in "Control Panel" anymore.

It is possible to set it in this way: "Start menu" -> Settings -> Find "Typing settings" -> Advanced keyboard settings -> check checkbox "Let me use a different input method for each app window"

Solution 2:

Please try this option, and then set your preference input method for different apps:

Start > Settings > Time & Language > Region & language > Additional date, time & regional settings > (under Language) Change input methods > Advanced settings > (under switching input methods) Check on "Let me set a different input method for each app window"

Solution 3:

As of 03.12.2020, using Windows 10 Pro, the option goes in:

Settings -> Devices -> Typing -> Advanced Keyboard Settings
