Running VMw 17.6.1 aok and running Manjaro linux which I installed 3 or 4 days ago. I noticed tonight that I could copy & paste from Guest to Host and visa versa, and I thought I was isolated. I opened VM | Settings | Options | Guest Isolation and found that both copy & paste boxes were ENABLED! I don't know (or recall) if prior versions were default with this disabled, but 8 previous VMs created with v16 (or v15) have this disabled. I know that I did not Enable them in this linux VM. I may have forgotten but had been thinking disabled is default, so suggest you check if this isolation is important to you. And what is the "threat level" of having copy & paste enabled.
