270 million. That's how many devices are now running Windows 10 already, according to Microsoft, at least. Considering the OS was launched just eight months ago, that might indeed be a world record, thanks to Microsoft rather aggressive, almost contentious, push. Unlike other Windows versions, however, Windows 10 isn't meant to be a completely finished product with minor "service pack" updates down the road. Instead, the "Windows as a Service" entails continuous updates, some of them quite major, during its lifetime. The Anniversary Update slated for summer this year is one such update and it will indeed be quite a big one.
