Windows 11: March Changes
Microsoft’s March preview KB5079391 landed with detailed servicing guidance for admins — including DISM and MSU install order tips for smoother updates. The broader Windows 11 March rollout also adds support for ultra‑high refresh displays (1000 Hz+), File Explorer improvements, Smart App Control tweaks, and a redesigned Feedback Hub and dark‑mode consistency work.

Microsoft published KB5079391 on March 26, 2026 as a non‑security preview for Windows 11, listing OS build numbers 26200.8116 and 26100.8116 for the release. (support.microsoft.com) The official support notes show Microsoft is distributing the update as a combined servicing stack update (SSU) plus the latest cumulative update (LCU), meaning the package delivered to devices includes both components together. (support.microsoft.com) Microsoft’s DISM documentation confirms administrators can install multiple.MSU packages in a single DISM command or add prerequisite packages in sequence when servicing an image. (learn.microsoft.com) Community reporting and forum parsing of KB5079391’s release files indicate the preview arrives as a package chain with prerequisite MSUs (users have flagged a dependency on older checkpoint updates in similar rollouts), which is why many administrators are using DISM or ordered MSU installs for offline deployments. (windowsforum.com) The update changelog spans dozens of fixes and refinements—security‑adjacent tooling and enterprise installation fixes are included—and independent outlets counted 29 changes in the preview package. (bleepingcomputer.com) Publishing notes and coverage say the release also resolves a year‑old WUSA network installation failure that primarily affected managed/enterprise workflows, and Microsoft shipped direct offline.MSU installers alongside the preview. (notebookcheck.net) Microsoft began rolling the refreshed Feedback Hub to Insider channels in mid‑March (the redesigned Home and submission flow started reaching Insiders around March 20, 2026), and company design leads have publicly acknowledged ongoing work to extend dark‑theme consistency across legacy system surfaces.
