I use Windows-7 in part of our backwards compatibility testing. As of Version 17 running OSX Monterey latest public release, Windows 7 nolonger functions: * Ping 8.8.8.8 works fine. * Ping google.com FAILS. * Network diagnosis -> DNS not responding. * Manually configure DNS, same results-- fail to look-up * Opening any kind of browser, results in process-lockup afterwards any attempt to resolve DNS. * Parallels tools now wants to install as some kind of 'legacy driver' requiring 'test signing enabled'. It never used to do that, and our anti-tampering will not permit the application to run when the operating system is in test-mode. Testing the EXACT SAME VM under Parallels 16 works fine. I have also tested this under a fresh Win7sp3-Ultimate ISO from Microsoft with the same results after install. All other OS's (Win8->11 work fine) I have also changed the networking from Bridged to Shared, etc.. same result. (Keep in mind, until I attempt to resolve an address via DNS, network IO works correctly, including Sharing between guest and host mapped drives)
