I moved to a brand new MacBook Pro and did a fresh install of Parallels Desktop 15, had a Windows 10 created and entered the new product key I purchased from the MS store. Using shared network as recommended, but Windows cannot access the internet, no matter what I try. This should work as I have not done anything to change the original installation and have not done any installs on Windows yet. I did NOT install Parallels Toolbox for Mac as I see no use for it on the Mac side. I did install them on Windows, but that did not solve the issue. It should be possible to do a fresh install of Windows 10 on a fresh install of Parallels 15 on a fresh MacBook Pro. Where is the missing info ?
