Fix ALT codes not working on Windows 11/10

ALT codes are used to enter special characters and symbols on your PC. These are combinations of the ALT key and the number keys. A specific ALT and numeric key combination is used to enter a specific special character. But some users cannot use ALT codes on their computer. This problem may be caused by your configured settings or a certain application interfering with your keyboard shortcuts. It could also be caused by a registry entry preventing you from using ALT codes.

Here are some fixes and suggestions:

1] Turn on the mouse keys while Num Lock is enabled.

2] Edit the registry to enable all Unicode characters.

3] Uninstall the problematic app.

4] Switch to another keyboard layout.

5] Use the character map to enter ALT codes.

6] Troubleshoot in a clean boot state.
