Pureinfotech says the November 10 security update is expected to deliver the same fixes automatically. **Takeaway:** KB5127936 is an optional, non-security preview, so most people can skip it and let the scheduled November 10 Patch Tuesday update bring the same changes automatically. **Key figures (as reported by the source):** - Changes and fixes in KB5127936: 41 - Builds after install (25H2 / 26H2): 26200.9818 / 26300.9818 - Scheduled November security update: Nov 10, 2026 If you want to know how to update Windows 11 this week, you have a real choice to make. An optional preview called KB5127936 is available right now with 41 changes and fixes, and the regular November security update is scheduled for Tuesday, November 10. You can grab the new features today, or wait a few days for the scheduled Windows 11 update to bring them automatically. The preview landed on October 29, 2026, [according to BleepingComputer](https://bleepingcomputer.com/news/microsoft/windows-11-kb5127936-update-released-with-41-changes-and-fixes), and it covers Windows 11 versions 25H2 and 26H2. It includes a reinstall option that needs no USB media, adaptive hibernation and a regrouped privacy page. Below are the exact steps, through Settings or by hand, what is in the package, and a straight answer on whether to install it now. One scope note: this guide is for PCs already running Windows 11, and it does not cover updating to Windows 11 from an older release. ### What is in the Windows 11 November update? The Windows 11 November update is expected to ship the features now sitting in the KB5127936 preview. [Pureinfotech describes the preview](https://pureinfotech.com/?p=193077) as an early look at the November 2026 Security Update, and says the November 10 release delivers these fixes and enhancements automatically. BleepingComputer puts it more loosely: the preview features are expected to reach all users in next month's Patch Tuesday, without giving a date. Since November 10 is the second Tuesday of the month, the two line up. None of that November release exists yet, so treat the list below as what the preview contains today. BleepingComputer reports these headline changes: - **Privacy & security page:** Camera, Microphone and Location controls are now grouped together. - **Wi-Fi in recovery:** the Windows Recovery Environment (WinRE) reuses eligible saved Wi-Fi profiles, including certificate-based networks. It is on by default and admins can turn it off. - **Restore Summary:** a Restore Summary appears after you restore a backup profile to a new device. - **Adaptive hibernate:** the PC hibernates less when the battery is above 80% and earlier when it drops below 10%. - **File Explorer:** the right-click menu is faster and can be customized for app extensions and commands. - **Xbox mode:** the refreshed Gaming Task View adds a navigation bar with Power Options and Exit to Desktop. - **Cloud rebuild:** Windows can be reinstalled using Windows Update content, with no USB media or custom image, even when Windows won't start. Pureinfotech's [Windows 11 feature history](https://pureinfotech.com/windows-11-feature-history-2026) lists more updates to Windows 11. Narrator can read and navigate math equations in supported Microsoft 365 apps and browsers. Magnifier gains contrast themes, per-monitor zoom and viewport locking. Hovering over a recent message in Start previews it, Edge launches faster, and the update brings a memory integrity expansion, IPv6 CLAT and Unicode 17.0 support. On the fix side, Pureinfotech lists repairs for Remote Desktop, Smart App Control, AMD graphics audio, Windows Sandbox, Always On VPN and WSL2 virtualization. One background item: BleepingComputer notes that the original 2011 Secure Boot certificates expire in late June 2027 and updated certificates are rolling out. Some devices may restart one additional time after a Secure Boot certificate update. ### How to update Windows 11 to the latest version in Settings The simplest way to get the Windows 11 update is the Windows Update page in Settings, and it also delivers the preview without a manual download. Because KB5127936 is optional, you opt in to it, and to update Win 11 this way you follow Pureinfotech's steps: 1. Open **Settings** and go to **Windows Update**. 2. Turn on **Get the latest updates as soon as they're available**. 3. Click **Check for updates**. 4. Click **Download and install**. 5. Click **Restart now** when it finishes. BleepingComputer adds that the preview shows up manually, through Check for updates, unless that toggle is on. When the PC comes back up, the build number tells you it worked. BleepingComputer reports build 26200.9818 for 25H2 and 26300.9818 for 26H2. If you would rather wait, do nothing. Pureinfotech says the November 10 security update delivers these changes automatically, and notes that some features roll out gradually, so a feature may show up on your PC a little later than on someone else's. ![A slim laptop charging on a wooden table beside a coiled power cable and a mug, the quiet setup for a Windows 11 update](/uploads/blog/how-to-update-windows-11-kb5127936/img1.webp) ### How to update Windows 11 manually To update Windows 11 manually, download the standalone package from the Microsoft Update Catalog and run it yourself. This route suits anyone who wants to install a specific KB on purpose. The steps, drawn from BleepingComputer and Pureinfotech: 1. Open the Microsoft Update Catalog in your browser. 2. Search for **KB5127936**. 3. Download the package that matches your Windows version and processor type (Pureinfotech's download list includes x64 and ARM64 packages). 4. Double-click the downloaded .msu file to run it. Pick the right file. Pureinfotech's direct-download section also lists packages under 24H2, but BleepingComputer and Pureinfotech's own feature history name only 25H2 and 26H2 as covered versions. If you run 24H2, check the KB page for your version before installing anything rather than assuming it applies. Also watch the KB numbers. The sources mix labels for last month's optional update (Pureinfotech mentions KB5127648 in one place and KB5124010 in another), and BleepingComputer covered the KB5127648 and KB5126653 cumulative updates on October 13. For this month's preview, the number to search is KB5127936. ### Is KB5127936 safe to install? KB5127936 is an optional preview, not a security patch. We did not review Microsoft's own release notes for this build, so check its support page for known issues before installing. What the two reports say shapes the decision. BleepingComputer states that preview updates contain no security patches, and Pureinfotech says you don't need to install it right away because the November 10 update delivers the same fixes automatically. So the answer is about trade-offs:
Install KB5127936 nowWait for November 10
What you getThe 41 changes and fixes ahead of November 10The same changes, expected through the regular update
Security patchesNone (previews carry none, per BleepingComputer)The November security update
EffortManual opt-in through Settings or the Update CatalogAutomatic through Windows Update
Best forSomeone waiting on a specific fix, such as the Remote Desktop or WSL2 repairsWork machines and anyone who just wants a stable PC
Our reading: if one of the listed fixes solves a problem you have today, installing the preview is reasonable. If your PC works fine, waiting a few days costs you nothing, because the preview adds no security protection you would otherwise be missing. ![A row of USB flash drives in a wooden desk tray next to a closed laptop, the kind of installer media that Cloud rebuild in the Windows 11 November update makes unnecessary](/uploads/blog/how-to-update-windows-11-kb5127936/img2.webp) ### How to update Windows 11 25H2 to 26H2, and which version you are on The sources behind this guide do not publish steps for moving a PC from 25H2 to 26H2, and we won't guess at a date or rollout schedule for that move. What they do confirm is narrower: KB5127936 is listed as an update for both versions, each with its own build afterward. That gives you a quick way to see where you stand. After installing the preview, a 25H2 PC reports build 26200.9818 and a 26H2 PC reports 26300.9818, according to BleepingComputer. The first digits, 26200 or 26300, tell you which version you are on. Separately, the preview's Cloud rebuild feature reinstalls Windows from Windows Update content without USB media, even when Windows won't start. Our guide on [how to reinstall Windows 11](/radar/how-to-reinstall-windows-11) walks through Cloud rebuild alongside the other reinstall options and which of them keep your files. ### What to watch next The date that matters is Tuesday, November 10, when the November security update is scheduled to arrive. Once it ships, watch whether the full preview list lands as expected, since Pureinfotech says some features roll out gradually rather than all at once. If you are on 24H2, watch for clear confirmation of which packages apply to your version before installing anything by hand. And keep the Secure Boot timeline in mind: the 2011 certificates expire in late June 2027, and updated certificates are already rolling out. For most readers, how to update Windows 11 this month comes down to one choice: opt in to KB5127936 now if a listed fix matters to you, or let November 10 handle it. ## Frequently asked questions ### How do I update Windows 11? Open Settings, go to Windows Update and click Check for updates, then Download and install, and restart when asked.

Go to the Microsoft Update Catalog, search for the KB number (KB5127936 for this month's preview), download the package for your Windows version and processor type, then double-click the .msu file to run it.

Pureinfotech adds fixes for Remote Desktop, Windows Sandbox and WSL2. ### Should I install KB5127936 or wait? Most people can wait.
