What you need to know
If you have two or more displays and set your machine to sleep, odds are the apps will change locations.
Microsoft is aware of the issue and is fixing it.
You can grab the fix right now if you're in the Windows Insider Program.
Windows users with more than one monitor have long suffered at the hands of random app reshuffles. You set your machine to sleep, then wake it up only to see everything on the desktop entirely rearranged. All your careful organization mattered not to Windows 10 — until now.
Multiple monitor setups can rejoice, as Microsoft has announced that it's aware of the issue and intends to fix it (via The Verge). In a Microsoft dev blog entitled "Avoid Annoying Unexpected App Rearrangement – Your PC Can Sleep Without Nightmares," post author Michelle Xiong details that the issue is technically referred to as "Rapid Hot Plug Detect (Rapid HPD)," and that multi-monitor headaches caused by it can be a thing of the past if you're in the Windows Insider Program.
