Ability to use Windows Home/Professional editions
Ability to use Windows Home/Professional editions - without an MSDN license. I'm not a dev so I don't have an MSDN subscription. I usually use Browserstack.com to test web apps - but it would be nice to purchase a few VM slots in standard windows versions so I can outfit them with some custom testing applications that Browserstack.com doesn't have - and maybe set them up with Selenium grid + webdrivers.
It would even be nice if we could use the Internet Explorer VMs provided by Microsoft here: https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
Obviously I would setup the Selenium on them myself - not suggesting that they come with Selenium preinstalled.
