Hi. I'm David, and I'm happy to help you.
Check if the keyboard layout is set correctly.
- Open Start and select "Settings > Time & Language > Language";
- Under "Preferred languages", select the configured language and click on "Options";
- Under "Keyboards", select "Add a keyboard";
- Select the keyboard layout for the keyboard you have.
- You can remove the unsupported layout by selecting it and clicking "Remove".
If the layout is correct, go back to the previous settings page and select "Keyboard" above "Windows display language".
Under "Override for default input method", change to your keyboard layout. Then uncheck the option "Let me use a different input method for each app window" if it is checked.
Feel free to ask back any questions.
