Microsoft releases KB5101681 for Windows 11 26H1 with calendar-based update pause
OS Build 28000.2608 brings the long-requested calendar pause, wider voice typing, and a push toward bi-monthly Insider previews.
The wait for a better way to stop Windows Update is over, at least for those brave enough to run the Pre-Release Insider channel. Microsoft dropped KB5101681 on July 28, pushing Windows 11 version 26H1 to OS build 28000.2608.
The headline addition? A calendar picker that lets you pick exactly when updates resume, up to 35 days out. No more guessing which week "two weeks" actually means.
Calendar pause lands, build numbers climb
This update isn't just a patch for current shipping Windows 11. The jump to build 28000 signals a fresh platform revision for the 26H1 cycle. Current versions like 24H2 and 25H2 sit on builds in the 26200 range. We're seeing a distinct separation here. Version 26H1 is sitting on the 28000.x series, while the rest of the fleet is still on the 26xxx track.
It's a significant platform revision. The jump in numbers alone suggests Microsoft isn't just adding features; it's reshuffling the foundation. Keep in mind that 24H2 Home and Pro editions will reach their end of updates on October 13, 2026. If you're not on 26H1 already, you might want to start looking at the upgrade path soon.
The calendar pause replaces the old "pause for X weeks" model. You select an end date. Need more time? Pick a new date and re-pause. It's more flexible than the previous radio buttons. It's arguably the most requested Windows Update feature in the last few years. Now we'll see if the implementation is as smooth as the concept.
What's inside KB5101681
Beyond the pause picker, there's a fair amount of noise in this build. Microsoft has shifted to a bi-monthly preview cadence for Insider builds in 2026. You'll see updates on the 14th and 28th now, with public builds getting monthly cumulative updates.
For those not on Insider, the corresponding update for 24H2 and 25H2 is KB5101684, released on the same day.
Here's what else is in the pile:
- Voice typing expands to French, German, and Spanish.
- Copilot quick actions now work for work and school accounts in File Explorer.
- Widgets go quiet: no more opening on hover, taskbar badges minimize by default.
- Screen Tint arrives for accessibility, offering a full-screen color overlay to reduce eye strain.
- PCs with more than 32GB of RAM get improved memory management for running larger local AI models.
- New printer installations use Internet Printing Protocol (IPP) by default.
- Touchpad right-click zones become customizable in Settings.
It's a rather crowded changelog. Some features like Screen Tint and the touchpad customization are welcome additions, though the Widgets changes feel like Microsoft trying to calm down a feature that never really settled in. The memory management tweak for AI models is noteworthy for power users, especially with the push toward local inference on desktops.
On a slightly darker note, the Secure Boot certificate expiration warning is still in effect. Devices without the newer certificates since June 2026 will keep showing warnings, even if they function normally. Microsoft's been pushing fixes, but if you haven't gotten the memo, your BIOS might still act up.
KB5101681 is currently Pre-Release only. The x64 package is roughly 4,039 MB, and the arm64 build sits around 3,315 MB. Head to the Microsoft Update Catalog or your Insider settings to grab it.
