Microsoft has released a second Windows 10X preview build for the Microsoft Emulator, which brings with it a number of new changes and enhancements to the OS. As Windows 10X is still in development, we're expecting more features and changes to show up before it's signed off as RTM, which we're hearing will take place in June or July this year.

This week's build is 19578, and in it is a number of minor enhancements such as a complete dark theme for the Control Center, along with a new File Explorer beta app and a (semi) working out of box experience. We go hands-on with all the new changes in our video, which you can watch via the embed above.

It's been about a month since the last Windows 10X preview build, so hopefully we'll be getting another Windows 10X preview build next month with more features and changes. I'm told to expect improvements to Search, and more perzonalization options, to appear in the builds before RTM is complete.
