Microsoft has announced a renewed focus on Windows performance and reliability. All of that will come from removing speed-up loops littered throughout the Windows codebase.
In a blog post, the company says, "We removed most of them while developing Windows 11, but you know how easy it is to fall back into bad habits. Developers added them back over time. And Co-Pilot didn't help. It was trained on an older Windows codebase, so every PR has a couple of those loops in random places. App startup, network requests, starting Edge, clicking a button in Edge, adding popup ads to Edge. You know, core functionality. It was easier to accept the PRs than convince Co-Pilot to remove them. Removing all those loops is a herculean effort and we hope to have more news to share by Q2 2027. Sooner if we can figure out how to stop Co-Pilot from adding them."
