I have new build gaming rig, runnign th elatest NVidoa drivers and regardless of whether the game is full screen exclusive or full screen windowed the mouse floats off onto the second monitor.
Reading these scripted responses form so-called MS support boils my blood as most of the things they request just does nothing.
One of the first posts said to disable all MS background process and all startup items... absoute rubbish. This is a Windows **** issue when using multiple monitors. Gaming windows are unable to become exclusive and lock in the mouse.
