Hi Mohammed,
I'm sorry to hear that the previous solutions did not work for you. Reinstalling the Windows OS may indeed be a possible solution to the issue, but it can be a time-consuming process and may result in data loss if not done correctly. Before you proceed with the reinstall, I would suggest a few more troubleshooting steps that may help:
Check if your keyboard drivers are up to date. Go to the manufacturer's website and download the latest drivers for your keyboard.
Run a virus scan on your computer. Malware or viruses can sometimes cause issues with the keyboard layout.
Try creating a new user account and see if the issue persists. This will help to determine if the issue is specific to your user profile.
If none of these solutions work, then reinstalling the OS may be necessary. However, before doing so, make sure to backup your important files and data to avoid any potential loss.
I hope these additional troubleshooting steps are helpful.
Best regards,
