My windows 10 pvm has ballooned to 82 GB. I don't believe I have that much installed or stored in the virtual machine. Windows 10 should take up about 20 GB, Office 16 should take about 3 GB and maybe another GB for quicktime/itunes/iCloud & Opera. I don't store any files in the VM. It should certainly under 30 GB. Why is it so big? I clicked compress but we're only talking about MB. Any ideas?
