I'm having a huge issue with Windows 10 and P12. I recently wiped my MacBook Pro (13inch, late 2014 model) to have a nice fresh install of my development tools. My old system was cluttered, but ran Windows 10 and Parallels 11 without issue. I purchased P12 and and installed on my machine, expecting the same performance and great experience I had with P11. Except this time, nothing works properly. Boot times are 5 minutes, start menu doesn't even open, can't run command prompt. pretty much maxes out my CPU. Did I do something wrong? It can't be hardware related as I ran the exact same setup on the older version of Parallels without an issue. Can I transfer my license from P12 back to P11 ? Hopefully someone can help.
