By default in Windows 11, if you are in a full-width input mode, such as Hiragana input, pressing the space bar will enter a full-width space.
If you want to enter half-width spaces directly even in full-width input mode, you can change the Microsoft IME settings so that you can always enter the space key in half-width.
How to set the space bar to always be entered in half-width characters
1. Press Windows Key + R to open Run, type the following command and press Enter:
ms-settings:regionlanguage-jpnime
2.The Microsoft IME settings will open, so click "General".
3. The "Space" item is set to "Current input mode," so click on it and change it to "Always half-width."
The settings are now complete, so press the spacebar to check.
How to set it in the registry
If you operate the registry incorrectly, it may cause problems such as the system being unable to start. Please make a backup in advance using system restore or similar, and proceed at your own risk.
