I am getting corrupted files including the SQL Server not starting when Windows 10 starts up and am unable to run some software. Windows 10 and Parallels 12 were installed on a new iMac computer from scratch - no migration. After consulting with Windows and software companies all point to Parallels. Deleted the VM, re-installed Windows on a new VM. It worked for a day then began having the same problems. Advice on where to start?
