Windows 10 is already available as a free upgrade for Windows 7 and 8.1. While there are millions who have already upgraded their systems this weekteam, Microsoft is reportedly hard at work on the next updates and fixes to the new OS. 
Some new features and improvements have already begun to develop, and there is certainly a plan for many more to come.
The first big collection of fixes will come with the Service Release 1 (SR1). Sources familiar with Microsoft's plans say the SR1 is slated to launch in early August, possibly as early as next week.
SR1 will not include new features, but will fix some of them themethose reported by users after installing Windows 10.
After initial fixes and updates, Microsoft will prepare an even larger collection of fixes that will include some new additions. The package will be released later this year.
Not sure, it's reportedly slated for October, and some of those additions will include a new Exchange app messages to complete the Skype service and support extensions for the Microsoft Edge browser.
"There's no one working on a Windows 11 computer right now, but there's a group of people working on some really cool updates to Windows 10 that Windows Insiders will see soon," said Microsoft Terry Windows CEO Myerson in The Verge.
Windows Insiders will begin to receive, new builds soon, and will be able to test new features such as Microsoft Edge extensions support that should be released within 2015.
"Windows Insiders will soon see extensions to Microsoft Edge"
Speaking at The Verge last week, Microsoft Edge Developer Drew DeBruyne revealed how extensions will work in the Edge browser.
Extensions will be JavaScript-based, and Microsoft tries to mimic exactly how Chrome manages extensions. The company's goal makes it easier for developers to port Chrome extensions to Edge extensions.
"We do a lot of work to support essentially the same APIs that Chrome supports."
Microsoft's special messaging application for Windows 10 will be in the Preview stage within the next few weeks. The messaging application will complete Skype in Windows 10, creating a more iMessaging and FaceTime service.
Microsoft plans to roll out this feature to Windows 10 users later this year, but Insiders will be able to try it out very soon. They will be able to make calls video and audio without the Skype app.
In addition to the above features and application updates, Microsoft is also trying to improve the battery life of devices running Windows 10.
Furthermore, Microsoft is reportedly working on a "Redstone" project for Windows 10 that will add more features from 2016.
