Microsoft has been releasing two major updates for Windows 10 each year and the next one is due sometime in October.
After the last major update, which came on the 10th of April this year, the focus has now shifted to the next version, 1809. This has previously been given the codename Redstone 5, but has now been named Windows 10 October 2018 Update.
The actual date for rollout has not yet been decided, but should arrive by the end of October. The update will include a number of new features for devices, such as a new cloud cutter synced between different machines, a dark theme for Explorer, an updated clip tool, Microsoft Edge enhancements, and performance information in the Xbox Game Bar.
We'll also see improved smartphone integration and more emojies, as well as some much-needed improvements to Windows Mixed Reality. Hopefully a feature that makes it more attractive to the ordinary user. We may, with a bit of luck even see some Hololens improvements.
Update: Microsoft has now paused the release of its next update due to problems which causes files to be lost. Is not yet known when the new update will arrive, but it may be delayed by weeks, if not months.
