Microsoft announced two distinct technology releases this week, targeting both gaming and computing history preservation.

The company released a new Xbox update that introduces several features, most notably the ability to disable Quick Resume for individual games. Quick Resume is a feature exclusive to Xbox Series X and Series S consoles that allows users to switch between multiple games with minimal loading times by preserving game states in memory.

While Quick Resume has been praised as one of the standout features of Microsoft's current-generation consoles, some users have encountered compatibility issues with certain games. The new update addresses these concerns by giving players granular control over which games utilize the feature.

Separately, Microsoft open-sourced what the company describes as "the earliest DOS source code discovered to date." The released code predates Microsoft's acquisition of the operating system that would become MS-DOS. The original code, known as 86-DOS, was developed before Microsoft purchased it and transformed it into one of the most influential operating systems in computing history.

The DOS source code release appears to be part of Microsoft's broader efforts to preserve computing history by making early software code accessible to researchers and enthusiasts. This follows previous releases of historical Microsoft software code for educational and archival purposes.

Both announcements reflect Microsoft's ongoing work in gaming technology improvements and technology heritage preservation, though they address completely different aspects of the company's operations.
