I have not used Parallels in a while and the true test will be once I install the only Windows program I still use (Autocad 2008). I hope it works as good as Fusion in that area. The Fusion install is decent but compared to Parallels it is not nearly as easy to use. I think the big difference is the company making Parallels only has a few products based around parallels. VmWare has so many other products it takes me a while just to find Fusion in the Community area. I imagine Fusion doesn't have the same priority that Parallels does for their companies. I would guess thats one of the reason they didn't release the new version along with the Windows 10 release? Theory crafting ...
Wow Parallels even does a Netplwiz to get rid of the login screen. Things I do anyways but its nice to see it done before I even touch it.
