Wzor has now truly opened the floodgates on 10031 bearing all but a physical leak of the x86 variant of build 10031 in a blog post, updated earlier today.
These past few days have shown us a new login screen, Spartan in action, and included in the build unfortunately (for many) the crappy 'new' Recycle Bin is also still there. Many will hope it doesn't make it into the RTM which is expected to roll out by June.
All of the images are from a Russian Windows 10 build, so some aren't too clear as to what we're seeing regarding Settings menus, but it does give us an idea what to expect soon.
All that remains is for Microsoft to deliver on their promise of a faster cycle of build releases for Insiders, which should mean we will get to play around with a new build sometime in the coming week.
For now though, you can check out the many images below in the gallery.
