Windows has a "high DPI" feature which lets users effectively use high DPI displays, in since Windows XP.
However, many applications implemented display scaling incorrectly. In Windows Vista, they added a backwards compatibility feature which scales the application as a bitmap, resulting in blurry controls.
I would like to make my application be high-DPI aware, which means testing in high DPI mode. But switching back and forth (and logging in/out) to check if the scaling code works correctly is annoying.
Is there some way to force my application to run in high DPI mode for testing purposes?
(I am well aware that the answer may be "you can't; sorry." I worded this as a "How..." question because I don't want someone to say "Yes" and say nothing else)

Wait, you work for Microsoft? You should be asking company experts about questions like these or posting on some internal mailing list and giving us useful tips and answers! – Karan – 2013-03-10T03:56:48.127
1@Karan: It doesn't work like that. It's a company of 40,000 developers; there's no magic system that lets one figure out exactly which of the other 39,999 one needs to talk with about a feature. Nor do people in the Windows group treat people outside the Windows group like insiders, even if I knew with whom I should speak. – Billy ONeal – 2013-03-10T04:08:26.563
Ah well, there goes our dream of obtaining answers to some really burning questions about Windows and its oddities! :) Was just hoping there might be a mailing list where you guys can at least post queries and hopefully receive informed answers. – Karan – 2013-03-10T04:20:34.800
@Karan: You're more likely to get answers posting comments in Raymond's suggestion box :) – Billy ONeal – 2013-03-10T04:36:51.753
Yeah, but the 2-3 year wait is a killer! Thankfully he does answer queries on SO, but of course those have to be programming-related.
