Windows 10 build 10031

Windows 10 build 10031 is a build of Windows 10, which was leaked to BetaArchive on 25 March 2017. This build continues the process of UI and UX refinement that was a major focus in the development of the operating system at the time. Project Spartan is not included in this build by default, as with all builds from the fbl_impressive lab before 10049, despite Microsoft's promise at MWC 2015 that it would be included in the next public build. It can only be assumed that Spartan was still undergoing final testing and evaluation before being incorporated into fbl_impressive builds, ready for release.

New features
The new lock screen available in builds 9860 to 10014 by editing a registry key, and enabled by default in 10022, has been enhanced in this build.

The only other major feature is a change that is most obvious in lower-end tablets. In this build, the gesture detection area has been increased to better suit both high and low-end tablet devices.

Other than this and the UX changes detailed in the next section, the changes known in this particular build are mainly under-the-hood improvements to stability and performance.

UI enhancements
Minor and major UI refinements continued to be made in these builds of the operating system, to provide a more cohesive experience. The Start button in this build has been reduced in size. The Metro-style menus seen in Windows 8.1 continue to assimilate those of the older variety. Transparency has been added to the Start menu and Start screen for the first time in a build from a branch destined for release to Windows Insiders. The iconography continues to be refined in this build, replacing many of the outdated icons from Windows Vista, 7, and 8. The new Recycle Bin icon first seen in build 10009 is still in place, although it has to be noted that the UI was not final at this point, and said icon was replaced a month later in build 10056.
