I use Parallels Desktop since version 3 (I guess), mainly to use the Proteus electronic design package from Labcenter Electronics on Macs. I never have had any incompatibility issue in Windows virtual machines.Parallels team, just continue evolving the product with this quality level. I would suggest to analyze what happens in the container technology, like Docker. I am sure, Parallels could add its value to create great solution for this technology as well.Cheers,AlexanderPrincipality of Andorra
