If a key is producing a different character, the keyboard layout is usually set incorrectly.
Try these steps in Windows 11:
- Press Windows + Spacebar to switch keyboard layouts.
- This often fixes cases where one printed character types another.
- Check the installed keyboard layout:
- Open Settings > Time & language > Language & region.
- Select the language in Preferred languages.
- Open Options.
- Under Keyboards, verify that the layout matches the physical keyboard.
- Example: United States vs United Kingdom.
- Remove the wrong layout if needed:
- In the same Keyboards section, remove layouts that are not being used.
- This prevents accidental switching.
- If multiple layouts are needed, switch between them when typing:
- Use Windows + Spacebar.
- In some Windows language features, Alt + Shift can also switch layouts.
If the goal is to change what a key types inside a Windows Forms app, handle the KeyPress event and set KeyChar to the character that should be entered.
