Anyone having issues with Windows Sandbox? It worked the first time, but then stopped working. (Says a file cannot be found) Like the group policy issue mentioned earlier, it only seems to happen on Enterprise, not Professional.
This update does include a known issue: After installing this update (KB4495666), users may experience error “0x800705b4” when launching Windows Defender Application Guard or Windows Sandbox. As a workaround, you can enable the following registry keys on the Host OS and reboot: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Containers\CmService\Policy] “DisableClone”=dword:00000001 “DisableSnapshot”=dword:00000001 if juste update , RTM already here but in testing ring with update for fix bug
