Hi. I used always (before test Windows SandBox in 1909) VmWare with Kaspersky isolation Virtual Machine (SafeMoney), together, never had problems. Now I tested, enable WSandBox and Kaspersky VM don’t work, I disabled Windows SandBox and Kaspersky Work (Test with identical images of particion dissk, restored from a Acronis’s Images maked befores activated WSandBox. If Windows SandBox is enables, and after disabled in THE SAME WINDOWS INSTALLATION, Kaspersky will never detect again a Vitual Machine options...). Thanks,
