I have a 27" iMac Late 2015 running macOs Sierra and PD 12.0.2. My iMac has the 1TB fusion drive with the 24GB SSD. After fresh installing Windows 10, it ran fine. Started to slow down after updates were installed. Sometimes, the VM runs extremely fast, but most of the time my disk usage in Windows is pegged at 100%. I have checked my settings in PD and it seems to be fine. I'm not really sure what is causing my high disk usage, especially when Windows is just idling, not running any programs, and not installing updates. Also, when the disk usage is at 100%, I can hear my Mac hard drive ticking away and is loud. First Aid found no issues with my disk. What can I check?
