Microsoft recently released Windows 10 build 10074. The company is reportedly continuing the development of its new software, and living proof is several new screenshots that have leaked and show the new Windows 10 build 10123. 
The photos reveal several new features, including improvements to the new Edge browser.
It is already known from rumors on the Internet that the next version will be called 10 build 1012x. It seems that it will be released very soon, through the Windows Insider program. But until then, let's see what the upcoming build will bring, from the leaked photos.
As you can see for yourself, Microsoft's Edge browser seems to be at the center of the company's developer development. It comes with support for private browsing mode, which will allow you to browse the web without saving history, cookies, or any other files.
At the same time, the browser now allows you to save passwords, so it comes with a built-in password manager. Also important is the ability to disable Flash Player in case you want to stay safe while browsing the web.
Cortana also appears to have a lot of new features in this build, so the next version will allow you to send your suggestions to the app's development team.
At this time, Windows 10 build 10123 appears to be mostly an Edge improvement build, as we can't see any improvements to the system from the photos.
For those who wish to try the new build of the operating system, be patient. Once it has been released, it will not be long before it reaches the internet, through official or unofficial channels.
