If you are developing a website on Linux or Mac you may want to check the behavior of the website in Windows with the Internet Explorer or with the latest Microsoft Edge web browser. I am developing the most projects local in a Docker container, a Vagrant box or for example on a local Apache server. Sometimes also with the build in webserver of PHP or grunt-contrib-connect. The type of local webserver is not that important, more important is the fact that the webserver is not reachable from outside. Developing on my Linux machine and switching to an Windows machine in my network to check the behavior of the website is no option as workflow. Luckily is Microsoft providing Free Virtual Machines from IE8 to MS Edge.
Chrome Firefox Linux VirtualBox Windows
When downloading a virtual machine at https://dev.windows.com/en-us/microsoft-edge/tools/vms/ I'm always getting a Unknown network error from my browser, in this case chromium. But I had the same experience with iceweasel.
