Windows 10 to be the last major version of Windows

I thought that's what they've been doing for years, except they released tiny patches that I frankly have no idea if they were a positive impact, a negative one, or even a needed one.

Windows service packs have traditionally been huge bugfix rollups with maybe a few behind-the-scenes feature updates. The new system is going to be more akin to OS X, where the free major updates also include major functionality changes.
