Thank you very much indeed.
Okay, I guess this may mean:
1. Update the VM's (3x Windows 10): Windows - check for updates
2. Remove the snapshots
3. Then copy the entire folder containing the 3 VM's to a new folder
4. Rename that one
5. Install VMware Player and use the VM's from the new folder
Wondering whether it may be useful to still keep the Pro version installed.
