Microsoft released frequent cumulative updates to improve the functionality of Windows 10 after launching its newest operating system. In August only, three cumulative updates were launched via Windows Update, including KB3081448, KB3081449 and KB3081452.

Currently, the tech giant is working on its first non-patch update for Windows 10, which is currently codenamed Threshold 2 (also known as Wave 2). The update was previously scheduled to launch sometime in October, but now this may have been pushed back about a month later than initially expected. However, the release date has been delayed in November according to a new report from Winbeta.

The news isn’t all bad, as this gives the company more time to further optimize the update and work on some new features before it is finally released. Microsoft shares nothing about what could be coming in this first non-patch update. However, in addition to system-wide optimization and tweaks, this Threshold 2 update is expected to include a new universal Messaging app for the desktop, extensions for Microsoft Edge and some performance fixes.

Microsoft’s first non-patch update for Windows 10 could be released by November this year instead of October, as initially planned.

However, these changes will be few and small as significant improvements and features are all saved for Microsoft’s next major update for Windows 10. It is called Redstone, which is scheduled for a 2016 release, will pack additional features for consumers and enterprises. The update will be available in two waves: the first version is expected in June 2016, and the second one is expected in October.

Microsoft’s very first major update is internally being referred to as “Windows 10 Update for November” or the “Windows 10 November Update”. However, it’s unclear if the tech giant will use these names when releasing the update, or release it as a general update.
