Microsoft has rolled out Windows 11 Insider Preview Build 26300.8085 to the Dev Channel, marking the update as KB5079483 for testers on Windows 11 version 25H2. This build was made available on March 20, 2026, and the details were shared on the official Windows Insider Blog.
Accessibility Improvements
This new preview isn’t a large feature release, but it does bring noticeable changes for Insiders, particularly in the areas of accessibility and feedback tools. Microsoft stated that features in the Dev Channel may be released gradually, and some updates might first show up for users who have activated the toggle to receive the latest updates immediately.
The most apparent change for users in this build is the resumed rollout of the Pointer Indicator, which is an accessibility tool designed for individuals with low-vision. Microsoft explains this option helps users find and track the cursor more easily, and it can be activated via Settings > Accessibility > Mouse pointer and touch. Additionally, it can also be toggled using the shortcut Win + Ctrl + Shift + X.
New Features and Fixes
Microsoft is further expanding the Windows Magnifier, which now has the capability to magnify protected content in this build. The company has also addressed a bug that caused the Network and Sharing Center to incorrectly display two active Wi-Fi connections after switching networks. Reliability for explorer.exe has been enhanced when closing the input flyout, and a glitch affecting fluid dictation options in voice typing settings has been resolved.
Build 26300.8085 brings a revamped Feedback Hub experience for Insiders participating in the Dev and Canary channels. Microsoft claims that the app now features a simplified feedback submission template, improved navigation, a new category for compliments, and options for private or public visibility. It also offers a more focused feedback surface for quick reports, alongside better tools for capturing and reviewing screenshots.
Known Issues
Microsoft clarifies that this build is based on Windows 11 version 25H2 via an enablement package, and emphasizes that features in active development for Insiders may be subject to change, removal, or may never be included in a final public version.
Furthermore, Microsoft has announced a new known issue associated with the March 2026 cumulative update KB5079473 for Windows 11. Some users might find themselves unable to sign into their Microsoft accounts in certain applications after the update is installed. On Microsoft’s support page, KB5079473 is associated with Windows 11 24H2 and 25H2, with OS Builds 26100.8037 and 26200.8037, released on March 10, 2026.
For users with Samsung devices, Microsoft has also identified a distinct known issue affecting some Samsung PCs following the February 2026 security update KB5077181 and subsequent updates. According to the company, this problem may render the C: drive inaccessible on select Galaxy Book 4 and Samsung desktop models. However, Microsoft notes that the issue arises from the Samsung Galaxy Connect app rather than Windows itself. The concern has been marked as mitigated after the affected app was temporarily removed from the Microsoft Store.
