We've seen info about some of the Windows 10 features like the new start menu and virtual desktops, but I haven't seen anything written about under the hood improvements. I remember when they were making Windows 8 they talked about a new USB 3.0 stack. Has anyone heard anything like this for Windows 10 from the dev team? You'd think they would be putting in stuff like performance improvements, better support for USB 3.1, Thunderbolt, PCI-Sata and m.2 Sata.
