Windows 11 KB5065789 was released on September 29, 2025, as an optional non-security cumulative preview update. On Windows 11 24H2 it produces build 26100.6725 and adds an AI actions menu to File Explorer, along with changes to Click to Do, Windows Share, passkeys, Narrator, gaming, and several system components.
However, KB5065789 is no longer the current Windows 11 24H2 update. As of August 9, 2026, Microsoft lists Windows 11 24H2 at build 26100.8875 with KB5101650, so most users should install the latest update offered by Windows Update instead of manually installing this archived preview. The downloads below remain useful for historical testing, controlled deployment, or troubleshooting a specific September 2025 build.

Microsoft’s complete release notes are in the official KB5065789 support article. The update applies to the editions covered by Windows 11 24H2 and 25H2; the Catalog separates the downloads by Windows version and architecture even though the 24H2 and 25H2 target files are the same x64 or ARM64 packages.

What the File Explorer AI actions actually do
After the feature reaches a device, right-click a supported image in File Explorer, or select it and press Shift+F10. The context menu can show an AI actions entry with up to four image-related commands:
- Visual Search: sends the image to Bing Visual Search through the web.
- Blur Background: opens the image in Microsoft Photos and applies a background-blur effect.
- Erase Objects: opens Photos and provides object removal tools.
- Remove Background: opens Microsoft Paint and creates a cutout of the main subject.
The documented image formats are .jpg, .jpeg, and .png. This is best understood as a new File Explorer entry point for existing Microsoft services and apps—not as one unified, entirely on-device AI engine built into File Explorer. Visual Search uses Bing, while the other actions launch Photos or Paint. Microsoft’s rollout announcement and the KB notes describe the feature and its staged availability.
Why the menu may be missing
Installing KB5065789 does not guarantee that the AI actions menu appears immediately. Microsoft distributed the experience through a gradual rollout, and availability also depends on the region, the selected file type, and the supporting Windows apps. The menu may therefore be absent even when winver shows build 26100.6725.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Check these conditions before treating the update as failed:
- The file is a
.jpg,.jpeg, or.png. - The device is not in the EEA, where the feature was unavailable at rollout.
- Photos, Paint, and Microsoft Edge are installed and updated where the action requires them.
- The rollout has reached the device.
- You are not confusing File Explorer AI actions with Copilot+ PC-only Windows AI components.
Other AI features and their eligibility requirements
KB5065789 contains several different categories of AI-related changes. They should not be treated as one feature with one set of requirements.
Windows AI components: Copilot+ PCs only
Microsoft lists updates to the following AI components:
| Component | Version |
|---|---|
| Image Search | 1.2509.1022.0 |
| Content Extraction | 1.2509.1022.0 |
| Semantic Analysis | 1.2509.1022.0 |
| Settings Model | 1.2509.1022.0 |
Microsoft explicitly limits these component updates to Windows Copilot+ PCs. They do not install on ordinary Windows PCs or Windows Server. A conventional x64 or ARM64 Windows 11 computer can still receive other parts of the cumulative update, including eligible File Explorer changes, but it should not be expected to receive every Copilot+ AI component.
Microsoft 365 document summarization
For supported documents stored in OneDrive or SharePoint, Microsoft 365 Copilot can provide a Summarize action without requiring the document to be opened first. This is not a free Windows feature available to every user. Microsoft lists all of the following requirements:
- An active Microsoft 365 subscription.
- A Microsoft 365 Copilot license.
- A supported Microsoft account or Microsoft Entra ID account.
- The document stored in OneDrive or SharePoint.
Without the required Microsoft 365 subscription and Copilot license, installing KB5065789 will not unlock document summarization.
Click to Do
On supported Copilot+ PCs, the update adds popular and commonly used AI action tags to the Click to Do context menu. It also makes Click to Do summaries shorter and more focused. Click to Do remains primarily a Copilot+ PC experience, so its availability should not be used as a test of whether KB5065789 installed correctly on a standard Windows 11 computer.
Other changes in the September 2025 preview
Move hardware indicators
Windows lets users choose a different position for the on-screen indicators used for brightness, volume, Airplane mode, and virtual desktops. The documented path is:
Settings > System > Notifications
Use Position of the onscreen pop-up. The available choices include top-left, top-center, and bottom-center, although the exact wording can vary by build or language.
Advanced Settings replaces For Developers
The redesigned developer page is located at:
Settings > System > Advanced
It brings together controls for File Explorer behavior, long-path support, File Explorer version-control information, and Git-related information for repository folders. Existing developer controls, including End task, are also included. Some of this functionality was part of a broader Windows rollout, so it may not appear immediately after the cumulative update is installed.
File Explorer improvements
Microsoft also lists these File Explorer changes and fixes:
- Faster loading of cloud files and context menus.
- Removal of colored backplates behind packaged-app icons in the Open With menu.
- Fixes for overlapping icons and text when increased text scaling is enabled.
- Correct mirroring of File Explorer panes for Arabic and Hebrew display languages.
- Fixes for unreadable extended Unicode characters in Recent-item tooltips.
Windows Share
Apps can be pinned as favorites in the Windows Share window, making frequently used sharing destinations quicker to access.
Passkeys
The update adds plugin credential-manager support for passkeys and provides a way to select a plugin passkey manager here:
Settings > Accounts > Passkeys > Advanced options
It also supports setting up a security-key PIN when the relying party uses User Verification = Preferred.
Notification Center and clock seconds
Notification Center becomes available on secondary monitors. The update also ties into the larger clock-with-seconds option introduced in the August 2025 non-security update.
Narrator and Braille Viewer
Braille Viewer support is added, and Narrator behavior in Microsoft Word is improved for lists, tables, footnotes, and comments. Enable Braille support through:

- On supported Windows handheld devices, a short press of the Xbox button opens Game Bar.
- A long press opens Task View.
- Holding the button continues to turn off the controller.

Known issues and later resolutions
Protected-media playback
At release, Microsoft documented problems affecting some Blu-ray, DVD, and digital-TV applications that use Enhanced Video Renderer, HDCP enforcement, or DRM. Symptoms could include copyright-protection errors, interrupted playback, unexpected stops, or a black screen. Streaming services were not affected.
KB5065789 addressed the EVR/HDCP portion of the problem, while Microsoft later said KB5067036 supplied additional DRM-audio improvements. If protected-media playback is important, a current cumulative update is preferable to stopping at this preview build.
IIS and HTTP.sys connection resets
Microsoft later documented an issue in which IIS websites or other HTTP.sys-based server applications could fail with connection-reset errors after KB5065789 on Windows 11 25H2, or after the October 2025 security update on Windows 11 24H2. A local IIS site could show:
ERR_CONNECTION_RESETMicrosoft marked this issue as resolved by KB5067036. Administrators can consult the Windows 11 24H2 resolved-issues page when diagnosing an affected deployment.
Recommended Free Tools
Missing password icon on managed devices
Some managed or enterprise environments could show a missing or invisible password sign-in option on the lock screen after KB5064081 or later. The password button could still be activated by hovering over and selecting its expected location. Microsoft later documented a fix in KB5074105. Home and Pro users on personal devices were considered unlikely to encounter this issue.
Checkpoint-related installation failures
Windows 11 24H2 uses checkpoint cumulative updates. When an administrator installs a cumulative update manually from the Microsoft Update Catalog, the required earlier checkpoint package may also be needed. For KB5065789, that checkpoint is KB5043080.
Windows Update and WSUS normally manage this dependency. A manual installation containing only the KB5065789 target package can fail because the applicable checkpoint is missing. The recovery procedure is:
- Confirm that the computer is running Windows 11 24H2 or 25H2 and identify its architecture.
- Download the matching KB5043080 checkpoint and KB5065789 target package.
- Put only those applicable packages in a clean folder.
- Install KB5043080 first.
- Install KB5065789 second, then restart if requested.
Microsoft explains the checkpoint model in its Windows 11 version 24H2 documentation and its Catalog checkpoint cumulative updates guide.

How to install KB5065789
Option 1: Windows Update
When KB5065789 was current, it could be installed as an optional preview update through:
- Open Settings.
- Go to Windows Update.
- Select Check for updates.
- If the preview appears under optional updates, select Download and install.
- Restart when Windows requests it.
Because the update is now superseded, a current system will normally be offered a newer cumulative update instead. That is the recommended path for ordinary users.

Option 2: Install the two .msu files individually
Create a clean folder such as:
C:PackagesPlace the two matching files in it. For x64, the order is:
1. windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu
2. windows11.0-kb5065789-x64_e3d377d0a97a3f7efaeec8f698d3040751f7da18.msuFor ARM64, use the corresponding ARM64 filenames:
1. windows11.0-kb5043080-arm64_df540a05f9b118e339c5520f4090bb5d450f090b.msu
2. windows11.0-kb5065789-arm64_f45774ce6dae382c5e6624d1b798d375b918db65.msuDo not mix x64 and ARM64 files or place unrelated .msu packages in the same servicing folder.
Install with DISM
Open Command Prompt as administrator and install the checkpoint first:
DISM /Online /Add-Package /PackagePath:"C:Packageswindows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu"Then install KB5065789:
DISM /Online /Add-Package /PackagePath:"C:Packageswindows11.0-kb5065789-x64_e3d377d0a97a3f7efaeec8f698d3040751f7da18.msu"For ARM64, replace both x64 filenames with the ARM64 filenames. Microsoft’s DISM package-servicing documentation describes the applicable prerequisite handling.
Install with PowerShell
Run PowerShell as administrator. The x64 example is:
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsAdd-WindowsPackage -Online -PackagePath "C:Packageswindows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu"Then run:
Add-WindowsPackage -Online -PackagePath "C:Packageswindows11.0-kb5065789-x64_e3d377d0a97a3f7efaeec8f698d3040751f7da18.msu"Replace the filenames with the ARM64 versions when appropriate. Microsoft documents this cmdlet in the Add-WindowsPackage reference. Its PackagePath parameter can also point to a folder containing applicable prerequisite packages.
Install both packages from a controlled folder
If C:Packages contains only the applicable KB5043080 checkpoint and KB5065789 target packages, DISM can discover the prerequisite from that folder:
DISM /Online /Add-Package /PackagePath:"C:Packages"Using a folder is convenient for checkpoint servicing, but it is important that the folder does not contain unrelated updates. Microsoft warns that unrelated packages can interfere with servicing or make the result difficult to diagnose.
Service an offline Windows image
For a mounted offline Windows image, install the checkpoint first or place both applicable packages in a controlled package folder. A DISM example for the target package is:

DISM /Online /Get-Packages | findstr 5065789A newer build may be displayed if the computer has already received a later cumulative update. That is normal. Cumulative updates supersede earlier updates and carry forward earlier fixes, so KB5065789 may not remain as a separate visible entry after a newer update is installed. See Microsoft’s Windows 11 24H2 update history for the cumulative-update model.
Should you install KB5065789?
| Reader or device | Recommendation |
|---|---|
| Ordinary home user reading this after newer updates are available | Skip the archived preview and install the latest update offered through Windows Update. |
| Home user in September or October 2025 who wants early fixes | Install only if you accept the risk of an optional preview and have a current backup. |
| Copilot+ PC owner testing Windows AI | KB5065789 may be relevant, but Copilot+ hardware, rollout status, region, and supporting app updates still determine what appears. |
| User who only wants File Explorer AI actions | Do not install an old preview solely for this purpose. The feature was gradual, region-limited at rollout, and depended on supported file types and apps. |
| Microsoft 365 user seeking document summaries | Install the update alone only if you need other fixes; summarization still requires an eligible OneDrive or SharePoint document, Microsoft 365 subscription, and Copilot license. |
| Enterprise administrator validating a deployment | Use the Catalog packages in a test ring, include KB5043080, and verify the build and business applications before broader deployment. |
| Production server administrator | Do not deploy an optional client preview simply for its AI features. Apply the current server-specific servicing guidance and update instead. |
In short, KB5065789 made sense when it was the September 2025 preview offered to systems that needed its fixes or features. It is not the best update choice for a current Windows 11 installation, and it was never a security requirement.
Can KB5065789 be uninstalled?
Microsoft states that the combined servicing-stack and cumulative package cannot be removed with:
wusa.exe /uninstallThe LCU can be removed with DISM after identifying its package name:
DISM /Online /Get-PackagesThen use:
DISM /Online /Remove-Package /PackageName:<LCU-package-name>The servicing stack update cannot be removed after installation. Removal should therefore be treated as a troubleshooting option, not a normal way to switch off one feature. Since KB5065789 is superseded, installing the current cumulative update is normally the better resolution for compatibility or security concerns.

Frequently Asked Questions
Is KB5065789 a security update?
No. KB5065789 is an optional, non-security cumulative preview released on September 29, 2025. It was intended for early testing of fixes and features, not as a required Patch Tuesday security update.

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallWhy does KB5065789 install but File Explorer have no AI actions?
The File Explorer AI actions feature was released gradually and was not available to customers in the EEA at rollout. It also requires a supported image format such as JPG, JPEG, or PNG, and the relevant rollout and app availability. Installing the KB does not guarantee that the menu appears immediately.
Can I install only the KB5065789 .msu file?
For a manual Windows 11 24H2 Catalog installation, download the matching KB5043080 checkpoint package as well. Install KB5043080 first and KB5065789 second, or place only those applicable packages in a clean folder for DISM to process. Windows Update and WSUS normally manage the dependency automatically.
What build does KB5065789 install on Windows 11 24H2?
It updates Windows 11 24H2 to OS Build 26100.6725. On Windows 11 25H2, it produces build 26200.6725. If the computer has a newer cumulative update, it may show a later build instead because newer updates supersede this preview.
The Bottom Line
Bottom line: KB5065789 was a legitimate September 29, 2025 preview update for Windows 11 24H2 and 25H2, not a security update. Its most visible change was the gradually rolled-out File Explorer AI actions menu, but those actions use Bing, Photos, Paint, or Microsoft 365 Copilot rather than representing one universal local AI system. Copilot+ hardware, Microsoft 365 licensing, region, file type, and rollout status all affect availability.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If you must deploy the archived build manually, use the official Microsoft Update Catalog, choose the correct x64 or ARM64 files, install checkpoint KB5043080 before KB5065789, and verify the resulting build. For a current Windows 11 PC, install the latest cumulative update instead; KB5065789 has been superseded.
