Windows 10 Build 10022 is a pre-release build of the Microsoft Windows 10 operating system. This build had screenshots leak on 2015-02-24. It is the first build to be either released or leaked from the fbl_impressive branch. Screenshots were leaked by WZOR, a reputable leaker. Project Spartan is NOT included in this build, as it has not met criteria required for it's release to Insiders as yet. In fact, this build contains mostly bug-fixes and under the hood changes, with little in the way of new features. The only known enhancement in this build is a UX refinement in Task View . It was widely speculated that this build would be the next released to Insiders (as of Feb 2015), however this has been confirmed to be purely speculation.
