Exploring Windows 11 Insider Preview Build 26120.1912
Windows Insiders, rejoice! The latest Insider Preview Build 26120.1912 (Dev Channel) has just been released. This update brings exciting new features and improvements that promise to enhance your overall experience. Let’s dive into what’s new and noteworthy.
What’s New?
One of the standout features in this build is the enhanced Windows Mobile Hotspot. It now supports 6 GHz connections, which offer faster speeds and reduced interference. However, this feature requires compatible hardware and updated drivers. Users can find this option under Settings > Network & internet > Mobile hotspot.
“The mobile hotspot will only use 6 GHz when explicitly enabled.”
Major Updates and Fixes
This update also includes a range of general improvements and fixes. For instance, there are enhancements to the Task Manager, which may have experienced a white background issue. Additionally, the Input Method Editor (IME) has received attention to address potential memory leaks.
Furthermore, the update adds attributions to text files for Rust open-source software components. This commitment to transparency is vital for developers and users alike.
Known Issues to Keep in Mind
As with any Insider build, some known issues persist. For example, clicking on a letter in the Start menu’s All apps list may cause it to break. If you encounter this, a simple reboot or restarting explorer.exe can resolve the problem.
“Features and experiences included in these builds may never get released as we try out different concepts.”
What’s Important to Know
Insiders in the Dev Channel receive updates based on Windows 11, version 24H2. Turning on the toggle in Settings > Windows Update allows users to access the latest features as they become available. However, not all features will make it to the final release, as Microsoft continuously tests and refines them based on user feedback.
In conclusion, this latest build showcases Microsoft’s commitment to enhancing Windows 11. With new features and ongoing improvements, Insiders have a unique opportunity to shape the future of the operating system. Stay tuned for more updates!
