It took me a long time to find a solution, but even after one hour or so I did not find a working shortcut/software to bring my mouse pointer to another screen.
Most of the tools out there were not working on Windows 10 and i did not like to install some macro-tools and try some selfmade scripts.
The solution mentioned above called "MousePointerReposition" is really worth it.
So if you are working on a PC with 2 Screens (or more) you should give it a try.
I am using a Stream Deck Device (Shortcuts to move Windows quickly between 2 Screens) to quickly move windows up and down between my 2 screens (using SHIFT+WIN+RIGHT) and togehter with MousePointerReposition it works like a charm.
