⚡ The Gist in 5 Seconds - The September Windows 11 update caused problems with Remote Desktop, USB audio, File History, and AMD GPUs. - An analysis of nine months of updates showed Windows 10 is noticeably more stable — it has had almost no mass regressions. - Windows 10 is supported through Extended Security Updates until October 12, 2027, so there's no reason to rush the switch. ### 🔍 What Was Found Windows Latest analyzed all monthly updates for Windows 11 and Windows 10 from January through September 2026. The September patch KB5124008 was released on September 8, and within days Microsoft confirmed or began investigating issues with Remote Desktop, USB audio, Linux/WSL (including the Claude Cowork app), and enterprise domains. The outlet also documented File History failures, Explorer.exe crashes, and AMD GPU instability. The emergency release KB5129195 on September 14 didn't fix everything. Over nine months, Windows 11 accumulated an impressive list of bugs: January — black screens and Outlook problems; March — Microsoft account sign-in failures in Teams, OneDrive, Edge, and Office; April — BitLocker and installation issues; May — error 0x800f0922 on systems with a small EFI partition; June — boot failures and BitLocker on HP PCs; July — a conflict with an Intel driver on Dell machines. Windows 10 over the same period had only a few limited incidents: a January shutdown failure on Secure Launch PCs, and BitLocker and Recycle Bin issues shared with Windows 11 in April and June. The September Windows 10 update KB5122878 is described as routine. ### 💡 Why It Matters The update comparison confirms: active development of Windows 11 with new features comes with a growing number of bugs. The September Windows 11 update closed a record 723 known vulnerabilities and simultaneously added a floating taskbar and new search — yet this very release turned out to be the worst in terms of regressions. For users, this means switching to Windows 11 right now is a lottery: you might get fresh features, or you might lose Remote Desktop or audio. The extension of Windows 10 support until October 2027 gives skeptics a legitimate way to avoid risking their working system. ### 🧩 Context Microsoft had planned to end Windows 10 support in October 2025, but extended the ESU program twice — it is now available to consumers and organizations until October 12, 2027. Thanks to ESU, Windows 10 continues to receive security updates but no new features. That's what explains the stability: Microsoft has simply almost stopped changing the system. Meanwhile, the company is betting on AI development — Distinguished Engineer David Fowler stated that "typing code is absolutely over." The rapid evolution of Windows 11 apparently conflicts with quality, and its 2026 update history is clear proof of that.
