A. Windows Copilot (Preview)

The most visible addition. Build 22631 includes the first iteration of Windows Copilot—an AI assistant integrated into the taskbar. It can summarize documents, change system settings, and launch apps. Note: Later builds (24H2) expanded Copilot, but 22631 was the first stable build to include it.

5. Dynamic Lighting (RGB without Vendors)

PC gamers using RGB peripherals often needed Corsair, Razer, or Logitech software. Build 22631 includes Dynamic Lighting under Personalization > Dynamic Lighting. It controls RGB on keyboards, mice, and fans (keyboard backlighting, mouse color) using the open HID LampArray standard.

7. The Future of Build 22631 (Support Timeline)

Microsoft supports each Windows 11 fall release for 24 months (Home/Pro) or 36 months (Enterprise/Education).

• End of Servicing (Home/Pro): November 11, 2025
• End of Servicing (Enterprise/Education): November 10, 2026

After these dates, Build 22631 will no longer receive security updates. Upgrading to 24H2 (Build 26100) will be mandatory. Microsoft has already begun automatically updating some 23H2 devices to 24H2 as of mid-2025.

E. Archive Support (Native)

Build 22631 added native support for additional archive formats:

• .rar (via libarchive open-source project)
• .7z
• .tar.gz

You no longer need WinRAR or 7-Zip for basic extraction.

6. Common Problems & Troubleshooting on Build 22631

Performance Verdict

Benchmarks from PassMark and UL Procyon show that Build 22631 performs identically to Build 22621 in CPU, GPU, and memory tests. The enablement package adds no performance overhead. If you experience slowness on 22631, it is likely due to third-party drivers or background apps, not the OS build itself.
