It is a common problem to all the users that mouse gets intermixed with the background such that we have to search for it over the entire screen.
This is a common problem to all the users of Windows in locating the mouse pointer. To have this problem solved, Windows have a default option which can locate the mouse pointer by showing a ring around it whenever Ctrl key is pressed but this thing works when a particular key is pressed.
To overcome this we have a tool called Sonar that displays a permanent ring around the mouse pointer thereby saving us from the problem of locating the arrow. What’s more interesting is that you can also vary the colour of the ring according to your choice.
The tool is free to use and you can also shut this feature off with a hotkey combination.
