Microsoft Halts New Features, Engineers 'Swarm' to Fix Windows 11 Performance Issues
Microsoft Engineers Focus on Fixing Windows 11 Problems

In a significant strategic shift, Microsoft has reassigned engineers from developing new features to focus exclusively on resolving the mounting performance and reliability problems plaguing Windows 11. The company has termed this intensive effort "swarming," and it is projected to continue for several months, extending through 2026.

Customer Feedback Drives Microsoft's Priority Shift

Pavan Davuluri, President of Windows and Devices, explained the rationale behind this move in a statement to The Verge. "The feedback we're receiving from our community of passionate customers and Windows Insiders has been clear. We need to improve Windows in ways that are meaningful for people," Davuluri said. He emphasized that throughout this year, Microsoft will concentrate on addressing consistent customer pain points, including enhancing system performance, reliability, and the overall Windows experience.

January 2026: A Month of Major Setbacks

The timing of this initiative is hardly surprising, given the turbulent start to 2026. In January alone, a security update rendered some business PCs unbootable, while a separate patch disrupted shutdown functionality. Microsoft was forced to release two emergency fixes—one to resolve the shutdown issues and another to address crashes involving OneDrive and Dropbox. All these incidents occurred within the first month of the year.

However, the problems extend far beyond monthly patches. Users continue to report sluggish performance in File Explorer, and dark mode still suffers from a persistent white flash bug—ironically introduced by Microsoft during an earlier attempt to fix it. In a revealing benchmark test conducted by a Windows enthusiast comparing every edition back to XP, Windows 11 failed to win a single performance test.

Microsoft Scales Back Aggressive AI Push

According to reports from Windows Central, Microsoft is quietly scaling back its aggressive integration of AI features. Copilot integrations in applications like Notepad and Paint are reportedly under review, and the company has paused work on adding new Copilot buttons to built-in apps. Even Windows Recall, the controversial screenshot feature announced in 2024 that sparked significant privacy concerns, is being reworked. There are unconfirmed rumors that Microsoft might even drop the Recall name entirely.

User Backlash Peaks in November

This pullback follows months of mounting user dissatisfaction, which peaked in November when Davuluri posted about transforming Windows into an "agentic OS" and received thousands of negative responses. The backlash highlighted growing frustration among users over stability issues and unwanted AI features.

One Billion Users Amidst Declining Trust

Despite these challenges, Windows 11 continues to grow. Microsoft CEO Satya Nadella confirmed this week that the operating system has crossed the one billion user mark, achieving this milestone approximately 130 days faster than Windows 10. However, analysts note that much of this growth is driven by Windows 10's impending end of support rather than genuine user enthusiasm for Windows 11.

Microsoft now faces a familiar challenge reminiscent of the Windows 8 era. Whether 2026 will bring a meaningful turnaround depends largely on how long the swarming effort persists and whether the implemented fixes prove effective in restoring user confidence and system stability.
