I've set up a Windows 8.1 VM under 8.1 as a test platform. Everything's working great, but I can't find one setting and it's driving me crazy. When I start the VM I get a pop-up asking me to set the display settings. I've found that if I click Save My Settings for Future Connections I can't find anywhere to later change them in the VM or in the Hyper-V manager settings. I chose a display configuration I wasn't happy with and could not find anywhere to change the configuration. Out of frustration I deleted the VM and created a new one. At this point I'm not saving my settings because I don't know how/where to change them if I want to later on. Here's a screen shot of the pop-up that I'm talking about.
Thanks for digging that up! That's one place I had not looked and/or maybe used the wrong search terms in Google. Isn't that nice of Microsoft to store the setting in an obscure location with no means for editing within the program itself!
