I am currently running a 2012 MBA, Parallels 11, and a Windows 7 VM...in the Windows 7 system tray there is an icon to upgrade Windows 7 to Windows 10...when I press/select the icon I get a message that Windows 7 cannot be upgraded because the Parallels Display Adapter (WDDM) is not compatible with Windows 10 (see the attached file images). I purchased Parallels 11 so that I could run Windows 10 and as such would greatly appreciate an explanation as to how make this happen. The other point worth noting is that I would ideally like to keep my Windows 7 VM and create/run a new/separate Windows 10 VM, is this possible. Thanks in advance.
Apologies for posting in the wrong forum and thank you for pointing it out...I have since posted in the Windows Guest OS Forum.
