Hi, LEWISCL
Welcome to Microsoft Community.
We understand your question about keyboard layout. It is important to explain that your keyboard layout is set by your computer manufacturer, and different computer manufacturers have different keyboard layouts for different models of their products, and there is no keyboard layout in Windows that is fully compatible with all laptop keyboards. As you described, no matter what keyboard layout you have set, it will affect the input of the other keys to a greater or lesser extent. For example, if you have set up the AZERTY keyboard layout, but when you press the M key, you will type coma.For this, we recommend you to contact Dell support to get the keyboard layout you want, or use a third-party software or keyboard to force your keyboard key mapping to achieve your desired keyboard layout.If you have any further questions, please feel free to contact us.
Best Regards
