How to make the mouse pointer left-handed in Windows 10

To make this change:

1. Open the Settings app by pressing the Windows logo key  + I on the keyboard.
2. In the Settings app, select ‘Devices’.
   
3. On the Devices screen, select ‘Mouse’ in the left-hand column.
4. On the right of the screen, select ‘Right’ from the drop-down menu labelled “Select your primary button”. This will swap over the mouse buttons so that you can now use the right click for selection and dragging.
   

Note: If this does not work it could be because your computer settings are managed by someone else (an IT department or administrator for example). If this is the case you will need to contact them to access these settings or for further help.
