How to make the mouse pointer larger in Windows 10

1. Open the Ease of Access settings by pressing the Windows logo key  + U. Alternatively, select the Start Menu > Settings > Ease of Access.
2. In Ease of Access settings, select Mouse pointer in the left column.
   
3. In the right column (see image above), adjust the slider labelled Change pointer size.

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