I've successfully installed Bootcamp on my Late 2013 13" rMBP, as soon as all of the Win10 drivers installed I noticed that the scaling was set correctly to compensate for the retina display. This changed when I mucked around the Display Settings in Windows 10 and dragged the 'Change the size of text, apps, and other items' option from CUSTOM to 175%. After setting it, I realized there was no way to set it back to the Bootcamp default. Does anyone have any clue as to what value Bootcamp set the scaling to before I messed it up? I can't find it anywhere. I know there's a registry key referenced here: http://pureinfotech.com/2014/10/18/...ing-virtual-machine-high-definition-displays/. I wonder if this registry key overrides the scaling in Display Settings, and if it's not set to a supported option (one that the slider can adjust to - 100%, 150%, 175%, 200%, etc.), it'll just say 'Custom'. I haven't a clue what this default value was set to previously, unfortunately. Thanks!
