At home I work with my Apple MacBook Pro with macOS Sierra. A nice feature in a multi-monitor setup is the “shake the mouse to find the mouse pointer”. The mouse pointer gets larger as long as you shake the mouse.
There is no such feature in Win7, but You can change the mouse settings to show an animated circle around your mouse pointer when you hit the CTRL key.
To enable this setting go to control panel, search for “Change mouse settings”. Open the tab “Pointer Options” and activate the checkbox “Show location of pointer when I press the CTRL key”. Voilá!
