Disable the Caps Lock key

If you frequently accidentally press the Caps Lock key and you feel it is not necessary, you can disable it. See Disable the Caps Lock key in Windows 11

Disable the Windows key

If you use a Macintosh computer, you use the Command key all the time. Unfortunately, on the Windows keyboard you will always accidentally hit the Windows key. This can be very frustrating, as pressing the Windows key with any of the cursor keys will resize the current window.

To disable the Windows key

• Download the 64 bit version of PowerToys by Microsoft (currently PowerToysSetup-0.68.1-x64.exe) from https://github.com/microsoft/PowerToys/releases/tag/v0.68.1
• Execute the installer file to install the application
• Start Powertoys
• On the left side select the Keyboard manager
  
• Click the Open Settings button
  
• Select Remap a key
  
• Click the plus sign
  
• On the left side select Win (Left), on the right side select Disable and click the OK button.
  
• Click Continue Anyway
