Those are identical installations otherwise?
I have a small Win10 installation here that is 21 GB, on a real machine.
A few small programs installed like McAfee, WinUAE and Amiga Forever but nothing massive like Office.
You can run Disk Cleanup as Administrator then can be rid of upgrade files if that is the difference here.
