Screenshots from Windows 10 build 10022 have leaked onto the internet from the upcoming public branch fbl_impressive. WinBeta understands that this build mainly focuses on under-the-hood improvements and doesn't include many new features.
It's likely that this build could be sent to Insiders next week, as 10022 is stable. Spartan is not included in this build, as Spartan is still not ready for primary usage and is missing a number of features.
It's unclear whether Microsoft is planning to ship this particular build to Insiders next week, however WinBeta believes 10022 is the likely candidate. Of course, that could change at any time. What are your thoughts on this? Leave them in the comments below.
