Very large PVM -- why?

[PaulKorm]

My Windows 10 PVM (Parallels 15) is 90.85 GB. The hard drive is 16.8 GB. "Snapshots" is 74.02 GB. There is a single snapshot in this PVM. I never change the HD space allocation. I only keep the single snapshot at a time. But the PVM keeps growing.

Seems out of control. What do I do to fix this?

One reason can be the addition of the Windows.old files left in the windows folder. Run explorer, properties, "clean up system files".
