Windows 11 Insider Preview Build 26120.1912: Key Features and Fixes

  • Thread Author
Hello, fellow Windows enthusiasts! Buckle up as we dive into the latest development in Windows 11, particularly for those who qualify as Windows Insiders. As of September 30, 2024, Microsoft has rolled out Windows 11 Insider Preview Build 26120.1912 (KB5043168) to the Dev Channel. This build is packed with new features, improvements, and a smattering of fixes that cater to those adventurous enough to test drive the cutting edge of Microsoft’s operating system.

What’s New in Build 26120.1912?​

This latest build introduces a myriad of changes and improvements, organized into two main categories:
  1. General Improvements: A collection of enhancements aiming to boost the overall experience on devices running this build.
  2. Feature Rollouts with Toggle Options: Users can opt-in to receive the latest updates as they become available through the toggle option in Settings > Windows Update.

Enhancements Highlighted in This Update​

Mobile Hotspot Support for 6 GHz Connections​

One of the most thrilling additions is the support for 6 GHz connections in the Windows Mobile Hotspot feature. However, it’s essential to note that this enhancement requires specific hardware and updated drivers. If you're equipped with compatible devices, you’ll find the option clearly labeled under Settings > Network & Internet > Mobile Hotspot.
  • Compatibility Reminder: Despite supporting 6 GHz, the mobile hotspot will default to the 5 GHz band unless explicitly enabled. So make sure your settings are optimized to harness this speed demon!

Various Fixes​

While new features are always exciting, addressing known issues is equally crucial. This update includes fixes for:
  • General Performance Enhancements: Improvements across various system elements, resulting in smoother operation.
  • Open Source Software: Added attributions for Rust OSS components.
  • Task Manager: Fixes a problem where the Settings page might display an unintended white background and addresses freezing issues during theme transitions.
  • Input Method Editor (IME) and WebView2 Applications: Fixes related to memory leaks and controller input detection, respectively.

Known Issues to Be Aware Of​

No software is without its quirks, and this build is no exception. Among the notable known issues:
  • Start Menu Glitches: Clicking on letters in the All Apps list could cause it to misbehave. If you encounter this, a quick reboot or restarting the explorer.exe process usually does the trick.

Reminders for Insiders​

For those in the Dev Channel, it's crucial to understand how updates are delivered. This build falls under Windows 11, version 24H2 via an enablement package. Many features roll out gradually, monitored via Control Feature Rollout technology, which begins with a small subset of Insiders before expanding based on feedback.
  • Feature Toggle: Windows Insiders can choose to be among the first to try out new features by enabling the toggle in the Windows Update settings.

For Windows Enthusiasts​

The Dev Channel is a playground for those eager to experiment with new innovations from Microsoft. However, with great power comes great responsibility. Users should remember that while some features may be fully developed, others might not make it to general release. Feedback from Insiders is not just welcome; it’s essential for shaping the future of Windows 11.
So, dear readers, how do you feel about these changes? Will you be toggling on your updates, or do you prefer to stick to stability over bleeding-edge functionality? Join the conversation, and let's engage in some lively discussion about the future of Windows together!

As we navigate through these updates, keep your devices secure and robust by staying informed and providing constructive feedback. Happy testing, Insiders!
