I have three Windows 10 VMs on my Mac. I was reclaiming disk space on them and two of them reduced as normal. The third wouldn't allow me because it said "Real Time Disk Optimization" was turned on. I decided to go into my settings and turn it on in my other two machines, but the option doesn't exist under either Options/Optimization or Hardware/Hard Drive in the preferences. In fact, I can't see the option in the VM for which it is turned on. Any ideas? Thanks!
