Bob recently upgraded an old Dell computer to Windows 10. He did an upgrade, which didn't work, then tried a clean install and it worked flawlessly. So he's quite happy to breathe new life into an old PC. Bob also likes the new backup and recovery feature. Leo says that Microsoft finally has backup down, and it's as good as Apple's Time Machine. He also says that Windows has profile based language support, so you can change languages by changing profiles, including Cortana.
