I recently started a new job, and due to the need to make VPN connections, I’ve been getting familiar with Hyper-V Manager. I’m using a laptop, so one of the first things I wondered was how I could fix the size of my virtual machine’s window so that I don’t have to do a lot of scrolling. Unlike with Remote Desktop Connection, where you can specify the size of the window before connecting, Hyper-V Manager did not appear to have such a configuration option.
It turns out the answer to my question is very simple: for a Windows 7 virtual machine, at least, all you have to do is change the screen resolution on the VM itself. To do that, right-click on the VM’s desktop and choose Screen Resolution (for Windows 7) or Display settings > Advanced display settings (for Windows 10) and choose a resolution small enough to fit on your physical computer’s display.
After you adjust your VM’s resolution, the window in which the VM is running resizes itself automatically, and you’re good to go.
