[QUOTE="Andy Ful, post: 829550, member: 32260"] Finally my Windows ver. 1809 decided to upgrade. Before upgrading, I set H_C, ConfigureDefender, and FirewallHardening to max settings. Furthermore, I activated Windows Defender Application Control with "Trust apps with good reputation" feature and whitelisted folders: c:\Windows and c:\Program Files... . I suspected that this could possibly break the upgrade, but everything went well.:giggle: After the upgrade, all H_C, ConfigureDefender, and FirewallHardening settings survived, but I had to reactivate WDAC. After this most applications in UserSpace (but not all) were still remembered as safe by WDAC. Anyway, some applications installed in UserSpace were blocked after upgrade (Grammarly desktop version and Privacy Eraser). I run them via [COLOR=rgb(0, 168, 133)][B]"Run By SmartScreen[/B][/COLOR]" and after that, they were accepted by WDAC. From my WDAC tests on Windows ver. 1809 it follows that using "[B][COLOR=rgb(0, 168, 133)]Run By SmartScreen[/COLOR][/B]" works well on simple applications, but may fail for the complex installations/updates. Such complex applications (like VirtualBox) must be installed in C:\Program Files... . [/QUOTE]
