Ive added guest additions but it doesnt let me copy and paste between host and guest

I am having trouble copying and pasting from host to guest. I am using Windows 10

Ive solved the problem. I went to device in the toolbar and enabled the shared clipboard

While I’m happy that you figured this out, I would encourage you to maximize your VM and pretend windows isn’t there.

Working between operating systems can lead to confusing situations. Working only in the VM will eliminate the possibility of those weird situations.
