Introduction

In January 2010, shortly after the release of Windows 7, the tech community was abuzz with the emergence of screenshots from a build labeled 7700.0.100122-1900. These images, initially shared by the Russian website WZor, sparked discussions about Microsoft's next steps in operating system development. Was this an early iteration of Windows 8, or perhaps a precursor to Windows 7 Service Pack 1? This article delves into the details of Windows 8 Build 7700, exploring its features, technical advancements, and the broader implications for Microsoft's OS trajectory.

Background and Discovery

The build in question, identified as 6.1.7700.0.winmain.100122-1900, surfaced on January 29, 2010, through WZor's website. The screenshots showcased an environment strikingly similar to Windows 7, leading to initial confusion about its purpose. However, the build number's progression from Windows 7's RTM build (7600) suggested a significant development milestone. (neowin.net)

Technical Insights

Build Identification and Features

Windows 8 Build 7700 retained the 6.1 kernel version, aligning with Windows 7, yet introduced several under-the-hood changes:

  • Internet Explorer 9 Integration: This build included an early version of Internet Explorer 9, still branded as Internet Explorer 8. Notably, this iteration was unstable, often crashing when switching to IE9 mode or loading HTML5 content. (betawiki.net)
  • Hardware Requirements: The build mandated support for Streaming SIMD Extensions (SSE), thereby dropping compatibility with older CPUs like the Pentium II. This requirement marked a shift towards modern hardware optimization. (betawiki.net)
  • Boot Manager Enhancements: Improvements included support for 800x600 resolution in the default boot screen and enhanced serial boot debugging capabilities. (betawiki.net)

System Components and APIs

  • Power Services Overhaul: The introduction of the User-Mode Power Services Extensions library (INLINECODE0 ) indicated a significant revamp of power management functionalities. (betawiki.net)
  • On-Screen Keyboard Updates: Internal code refactoring led to the addition of a new INLINECODE1 library, enhancing the On-Screen Keyboard application. (betawiki.net)
