Satbeer is an accountant and he uses some old programs sometimes. On his Windows 7 Ultimate system, he can still use XP mode. Is that secure? Leo says yes, because Windows 7 is still handling the backend while XP is virtual.
Dwayne misses the days of having an actual user manual. Leo says those days are long gone. Everything is to be found online. Dwayne also says there's an app for Android he wants to put on his computer. Is that dangerous?
Leo says that Android is safe because it's largely an emulator that runs programs, so it's easy to run Virtual Machine, or Bluestacks and run it. But it's a bit disappointing because emulators don't use the Google store, so the availability of apps is limited. He could sideload the .APK file, though.
