Date: 2015dec17 OS: ReactOS Q. What's the best way to try out ReactOS with VMware? A. I tried installing their plain .iso and it didn't work so well. Then I noticed they have a release preinstalled on a VMware machine. https://www.reactos.org/download This worked much better for me. To use it: - Download and unzip - In VMware, click on "Open a Virtual Machine" and browse to the .vmx file that was just unzipped Surprisingly they have the OS type set to Windows XP Professional. I would have expected Windows NT.
