Microsoft’s next annual Windows release, version 26H2, is expected to reach regular PCs around October 2026, and for machines already on Windows 11 24H2 or 25H2 it will arrive as a 174 KB enablement package that installs with a single restart. Microsoft confirmed the delivery model on its Windows IT Pro Blog, and preview builds are already running in the Insider program’s Experimental channel under the 26300 build series.
The tiny download works because 26H2 sits on the same Germanium platform as 24H2 and 25H2. The new code already flows to those systems through monthly updates and waits there dormant; the enablement package simply switches it on and moves the build number to 26300. PCs on 23H2 or Windows 10 do not share that servicing branch and face a full upgrade of roughly 6.5 GB instead. Hardware requirements stay where they are, so any machine running 24H2 or 25H2 today qualifies.
One naming wrinkle deserves a flag. Devices running Windows 11 26H1, a separate release that sits on a different Windows core, cannot move to 26H2 at all. Microsoft says those systems will get a path to a later release instead.
The feature wave tied to the 2026 cycle is the bigger half of the story, and much of it lands on 24H2 and 25H2 through monthly updates before 26H2 itself goes live. That explains why early reports called 26H2 an empty update while later ones listed a pile of changes: the package adds nothing by itself, but the year’s changes all count toward it.
The most visible change is the taskbar, which can be docked to the top, bottom, left, or right edge of the screen for the first time since Windows 11 launched in 2021. A smaller layout also shrinks the bar and its icons. Both options live under Settings, then Personalization, then Taskbar behaviors, with a live preview before you commit.
The Start menu picks up preset sizes plus separate toggles for the Pinned, Recent, and All sections, so the parts you never use can disappear. A new privacy setting hides your account name and picture while you share your screen during meetings or streams.
Search gets its biggest revision yet
Windows Search gets its largest revision since launch. Two independent switches under Settings, then Privacy and security, then Search turn off web results and Microsoft Store suggestions for a purely local experience. Local files now match from as few as two characters, misspelled queries succeed more often, and apps, settings, and files rank above web results when they are the better fit.
What changes for managed PCs
Managed workplace PCs get a quieter change. On eligible Microsoft Entra devices outside regions covered by the EU’s Digital Markets Act, Windows settings backup flips from opt-in to on by default, capturing system settings and the Microsoft Store app list so a reset or reimaged machine comes back familiar. Personal files stay out of it, since OneDrive handles those separately, and restoring a backup still requires an administrator to set it up.
What to do before October
If you run 25H2, nothing needs preparing. The features drift in through monthly updates, and the version bump can wait until Windows Update offers it. If you run 24H2, one date matters: support for that version ends on October 13, 2026, so take the one-restart upgrade when it appears rather than putting it off. The whole thing downloads faster than a single phone photo. Anyone on 23H2 or Windows 10 should plan for the full upgrade and check compatibility first. Installing 26H2 resets the support clock to October 2028 for Home and Pro editions, which is the real prize of an otherwise invisible update. We will cover the general availability release in our Operating Systems coverage when Microsoft sets the date.
