I have just found this amazing software, Mouse without Borders from Microsoft Garage, that allows me to move my pointer off the right-hand edge of my desk-top screen and onto the left-hand edge of my laptop to take control of it. I can then use my desk-top keyboard to type on my laptop. The process works in reverse too (i.e. I can control my desk-top PC from my laptop touchpad & keyboard.) I could do this with up to four PC’s if I wanted. These are the controlling windows:
Initially when you install the software on PC1 you are given a security key and the name of that PC so you can enter them on PC2 when you install the software on that one.
You can get the software for free here: Microsoft Garage – Mouse without Borders
What are the benefits you ask: Well I can just drag a file from one PC to the other. I don’t have to keep moving to the keyboard of the other to control it.
