Microsoft is fixing multiple monitor support in Windows 10 so it remembers window positions Working with multiple monitors is great -- in theory. The extra space is obviously useful, as is the ability to use different screens to group together related apps, documents and windows. Sadly, Windows 10's implementation of multi-monitor support is a little flawed, particularly when using DisplayPort. Many people with two or more screens will have experienced a problem that sees app windows being randomly rearranged, particularly after a system wakes from sleep. But this should be coming to an end as Microsoft is finally addressing the issue.
