When Microsoft announced Windows 10, it also made the shocking claim that Windows 10 was going to be the last version of Windows. Similar to Apple's OS X, Windows 10 is a foundation that's going to be continually upgraded to add new features and enhancements.
In theory, instead of waiting three to five years for a massive new operating system with a ton of changes, you get them as they're ready. So far that seems to be working out for Microsoft. It released one major update, update 1511 or Threshold 2, in November just four months after Windows 10 arrived. It's been nearly four months since then, so when is the next major update set to drop?
The next major update, dubbed "Redstone," was originally set for a two-part release in the summer and fall of 2016. It's going to make Windows 10 run better on mobile hardware, plus add support for Microsoft's HoloLens augmented reality system, Xbox One and other parts of the Microsoft ecosystem.
However, rumors are swirling that Redstone has been pushed back to sometime in 2017. Microsoft hasn't confirmed the news, but we wouldn't be surprised if it were true. In the meantime, Windows 10 users will still get monthly security updates, as well as other minor system tweaks, such as upgrades to Cortana, Microsoft's personal digital assistant.
