Windows 10 is just around the corner, and insiders will get the final bits on July 29 (with Windows 7 and 8.1 upgraders to receive it soon after that), but Microsoft is already working on the very first update for the new operating system.
We already knew that an update for Windows 10 was very likely to come sometime in October, but Neowin now reports that Microsoft internally calls this update Windows Threshold Wave 2 and plans to include performance optimizations and other fixes supposed to enhance the experience we get with Windows 10.
In other words, this eagerly expected update might not bring new features, but only a number of improvements based on the feedback that Microsoft receives after the July 29 release date of Windows 10.
If this is true, then Microsoft might be planning several other important updates for Windows 10, as the company has already confirmed that some features that weren't ready for RTM will be shipped later to everyone who installed the new OS.
One of these features is extension support for Microsoft Edge, a thing that would help the new browser better compete against its rivals and thus give users more control over the app.
Previously, it was believed that extension support for Edge would arrive in October, but if Microsoft is indeed planning to focus exclusively on optimizations and improvements with this update, then the new browser could get such functionality with another release that might arrive sooner or later.
As you can see, there are lots of uncertain details right now, so don't take anything for granted until we hear something official from Microsoft. But without any doubt, an update for Windows 10 is already being developed and it should arrive later this year, most likely in October, either together with Windows 10 Mobile or shortly after that.
