Microsoft has released Windows 11 Insider Preview Build 28020.1546 (KB5074176) to users in the Canary Channel, focusing on reliability improvements rather than new features. The update began rolling out on February 4, 2026, and targets early testers who want to preview platform-level changes ahead of broader Windows releases.

Windows 11 Canary Build 28020.1546 Update: What Changed
This Canary build delivers a small but important set of fixes aimed at improving everyday usability for Insiders:
Resolved app issues with OneDrive and Dropbox
- Microsoft fixed a bug that caused problems when apps worked with files stored in OneDrive or Dropbox. After installing this build, file access and cloud-based workflows should behave more reliably for affected users.
General stability and quality improvements
- The update includes under-the-hood fixes designed to improve overall system stability while running this pre-release version of Windows 11.
Known Issue: Incorrect Desktop Watermark
Microsoft has confirmed that the desktop watermark currently shows the wrong build number in this release. The company says this is a known issue and will be corrected in an upcoming Canary build.

What Windows 11 Canary Channel Users Should Know
Canary Channel builds represent the earliest stage of Windows platform development, and Microsoft notes that:
- These builds can be unstable and may include bugs, performance issues, or incomplete features, as Canary Channel releases are early development builds with limited official documentation.
- Features introduced in the Canary Channel are experimental and may change over time, be removed entirely, or never reach public versions of Windows 11.
- Updates often roll out gradually through Microsoft’s Control Feature Rollout system, which means not all Insiders will see the same changes at the same time, even on the same build.
- Leaving the Canary Channel later requires a clean installation of Windows 11, as users cannot downgrade directly to lower Insider channels due to technical limitations.
Microsoft also reminds users that the desktop watermark is normal for Insider preview builds and that some features may appear first in Dev or Beta channels before reaching Canary testers.
Windows 11 Build 28020.1546 is a maintenance-focused Canary update that improves app reliability when working with OneDrive and Dropbox files. While it does not introduce new user-facing features, it addresses real-world issues that affect daily workflows for Insiders testing early Windows 11 builds.
