I bought one of these directly from Dell.  I was surprised by how slow it seems to run with Windows 10 Pro. ("Only" 8GB of RAM.)I had been running windows apps in Windows 7 inside Parallels on my 2012 macbook pro and that environment gave faster response times than this Dell 3668 purchased in 2017. (Admittedly, the MBP was a much more expensive system.)  Maybe moving up to 16GB of RAM would help.Anyway, I recommend you avoid this system.
