Hi Mvikeli Dlamini,
Thanks for reaching out to Microsoft Q&A Forum. I understand that your space bar is not inserting spaces between words when typing on Windows 10.
Please make sure you already tried the Q&A Assist steps shared above. In addition, please try the following.
Before we proceed, I would like to narrow this down a bit:
1, Does the issue happen in all apps (for example, Notepad, web browsers), or only in a specific application?
2, Does the space bar work correctly when using the On-Screen Keyboard?
In the meantime, you can try these steps:
1, Turn off accessibility typing features that may affect keystrokes
- Press the Windows key, search for Ease of Access keyboard, and open it
- Turn off Sticky Keys, Filter Keys, and Toggle Keys if any of them are enabled
2, Check and reset the keyboard input language
- Press the Windows key, open Settings, then go to Time & Language
- Select Language and make sure only the intended keyboard/input method is installed
- Remove any unused keyboard layouts and restart the PC
3, Test with a clean boot to rule out background software conflicts
- Press Windows + R, type
msconfig, and press Enter - Under the Services tab, check Hide all Microsoft services, then click Disable all
- Restart the PC and test the space bar
4, Run system file checks
- Press the Windows key, search for Command Prompt, right-click it, and choose Run as administrator
- Run
sfc /scannowand wait for it to complete - Restart the computer after the scan finishes
5, Check for pending Windows updates
- Press the Windows key, open Settings, then go to Windows Update
- Install any available updates and restart the device
