Microsoft quietly released a targeted component update for Copilot+ PCs this February: KB5079253 advances the Image Transform AI component to version 1.2602.1451.0, and — like its immediate predecessors — is delivered automatically through Windows Update to eligible Windows 11 devices running version 24H2 or 25H2 that already have the latest cumulative update installed.

The Image Transform AI component is one of several modular AI packages Microsoft ships separately from the OS cumulative updates for Copilot+ machines. At a functional level, Image Transform powers the generative erase-and-fill primitives used by built-in apps such as Photos, Paint (Cocreator/Fill/Erase) and other Studio Effects workflows: select a foreground or object, erase it, and the model generates a plausible background to fill the gap. The KB text for KB5079253 reiterates this exact capability and lists the new component version as the visible artifact users can confirm in Update history after installation. (support.microsoft.com)
This release follows Microsoft’s ongoing cadence of small, hardware-targeted AI component updates for Copilot+ devices. That pattern — incremental component updates delivered independently of large feature or cumulative updates — has been used repeatedly in 2024–2026 to tune on-device models for different silicon (Qualcomm, Intel, AMD) and to address quality, accuracy, and performance of on-device AI features. Industry coverage and prior KBs show this steady, iterative approach.
For creators and power users, iteration on the Image Transform component can reduce the amount of manual touch-up required after an automated erase, making the built-in Photos and Paint experiences more credible alternatives to third-party tools for quick edits.
Because Image Transform performs generative inpainting locally on Copilot+ devices, the release likely contains one or more of the following:
Caveats and notes:
If you rely on Image Transform for production workflows, validate the update on a test device and keep a rollback/backup plan for mission-critical edits. For everyone else: update, test, and enjoy slightly smarter on-device editing — just be mindful of drivers, staged rollout, and the fact that these KBs rarely contain deep technical changelogs, so real-world testing remains the most reliable verification method.

Background
The Image Transform AI component is one of several modular AI packages Microsoft ships separately from the OS cumulative updates for Copilot+ machines. At a functional level, Image Transform powers the generative erase-and-fill primitives used by built-in apps such as Photos, Paint (Cocreator/Fill/Erase) and other Studio Effects workflows: select a foreground or object, erase it, and the model generates a plausible background to fill the gap. The KB text for KB5079253 reiterates this exact capability and lists the new component version as the visible artifact users can confirm in Update history after installation. (support.microsoft.com)This release follows Microsoft’s ongoing cadence of small, hardware-targeted AI component updates for Copilot+ devices.

What KB5079253 actually says (and what it doesn’t)
The public KB article for KB5079253 is concise and follows Microsoft’s standardized component-update template:- Applies to: Windows 11 version 24H2 and 25H2 (all editions) on Copilot+ PCs only. (support.microsoft.com)
- What it does: The article confirms the Image Transform AI component “can be used to erase a foreground and object and fill in the space with a generated background.” (support.microsoft.com)
- Delivery: “This update will be downloaded and installed automatically from Windows Update.” (support.microsoft.com)
- Prerequisite: You must have the latest cumulative update for Windows 11, version 24H2 or version 25H2 installed. (support.microsoft.com)
- Replacement note: KB5079253 replaces the previous Image Transform component update referenced under KB5077533. (support.microsoft.com)
Why this matters: functional impact for users and creators
For end users, the change you will observe (if any) is subtle improvements to the quality and reliability of generative erase and fill operations inside Photos, Paint, and other built-in experiences. Improvements typically translate to:- Better foreground/background segmentation when selecting objects for removal.
- Fewer visible seams or repetitive artifacts in generated fill regions.
- Faster on-device inference on machines with NPUs and properly tuned drivers.
For creators and power users, iteration on the Image Transform component can reduce the amount of manual touch-up required after an automated erase, making the built-in Photos and Paint experiences more credible alternatives to third-party tools for quick edits.
The delivery model and enterprise implications
Microsoft distributes these AI components primarily through Windows Update, not as standalone, user-driven application updates. KB5079253’s KB text explicitly states the update “will be downloaded and installed automatically from Windows Update,” and that the device must have the latest cumulative update for the relevant Windows 11 branch installed. That means:- Individual Copilot+ devices receive the update automatically; end users don’t need to take action in most consumer scenarios. (support.microsoft.com)
- Enterprise administrators should expect this update to follow the same delivery channels as other component updates, but the KB does not state explicit support for manual catalog downloads or WSUS-based targeting in its short text. Historically some AI component updates appear in the Microsoft Update Catalog while others are only shown through Windows Update; your mileage may vary. If precise rollout control is required, admins should monitor the Release Information for AI Components and Microsoft’s servicing announcements.
- Check a test device: Settings > Windows Update > Update history; look for the Image Transform version entry (KB5079253, version 1.2602.1451.0). (support.microsoft.com)
- Use built-in reporting: Windows Update for Business/Intune and other telemetry channels to track which devices have installed the component.
- If a device fails to get the component, ensure the device has the latest cumulative OS update for its branch and that no device policies block optional component servicing.
Technical anatomy: what “Image Transform v1.2602.1451.0” likely represents
Microsoft’s on-device AI stack is modular: Image Transform is one component responsible for inpainting and border-aware generative fill; Image Processing handles scaling, foreground/background extraction, denoising and pre/post processing; Phi Silica handles local language model tasks on copilot-capable hardware. Version tags like 1.2602.1451.0 are Microsoft’s internal package identifiers for the component model and runtime bundle. While a public KB won’t decode the internal versioning scheme, the numbering progression and prior KBs show that Microsoft ships small, incremental model updates several times a year to improve quality and to better map workloads to vendor NPUs and drivers.Because Image Transform performs generative inpainting locally on Copilot+ devices, the release likely contains one or more of the following:
- A refreshed model checkpoint (improved weights) for inpainting.
- Improved segmentation heuristics to better separate foreground and background boundaries.
- Performance optimizations to reduce CPU/NPU latency or to lower memory usage.
- Vendor-specific runtime binaries or accelerated kernels for better offload to NPUs/accelerators.
Privacy and moderation: what runs locally and what may go to the cloud
One repeated selling point for Copilot+ features is on-device processing: many generative operations, including erase-and-fill for images, are executed locally on the machine’s NPU or GPU when the device is Copilot+ capable. This reduces latency and keeps user images on-device by default. Coverage and Microsoft statements from product updates indicate that many image-editing features run locally and that web services are used for content moderation or to supplement capabilities only when necessary. That hybrid privacy model is an intentional design choice for speed and data minimization.Caveats and notes:
- The KB for the component itself does not include a privacy or telemetry breakdown; for details, review Microsoft’s privacy and AI-in-Windows documentation and any per-app privacy settings. (support.microsoft.com)
- If a generative operation calls out to cloud moderation, that will usually be documented at the feature or app level (for example, Photos or Copilot settings), not in a short component KB. Users who handle sensitive imagery should confirm app-level privacy settings and corporate policy before using generative features.
Risk assessment: what could go wrong
Every incremental model or runtime update brings a small risk profile that administrators and advanced users should track:- Regressions: Visual artifacts, degraded fill quality or new edge-cases where a previously reliable erase workflow produces worse output. Historically, Microsoft responds to regressions with follow-up component releases or cumulative fixes.
- Compatibility: Driver or firmware mismatches (graphics, NPU drivers) can cause slower inference, crashes, or the feature falling back to CPU modes. Ensure OEM drivers and Windows cumulative updates are current before expecting the best on-device experience.
- Rollout variance: Not all Copilot+ devices see updates at the same time; Microsoft often targets pilots, regions or silicon variations first. Expect staged rollouts.
- Visibility: Microsoft’s KBs for components are intentionally short. If you need deeper validation for enterprise change control, the KB alone is not a changelog — rely on test-device validation and vendor release notes.
How to confirm the update and basic troubleshooting
Short checklist for consumers and admins:- Confirm prerequisites: make sure the device is a Copilot+ PC running Windows 11 24H2 or 25H2 and has the latest cumulative update installed. The KB lists this as a prerequisite. (support.microsoft.com)
- Check Update history: Settings > Windows Update > Update history. The entry you should see after installation is “Image Transform version 1.2602.1451.0 (KB5079253).” (support.microsoft.com)
- If the entry is missing: reboot and re-check Windows Update; verify the device meets the Copilot+ hardware and OS criteria; confirm vendor drivers are updated.
- If the feature appears degraded: collect repro screenshots, check Event Viewer for relevant errors (app crash or driver issues), and consider filing feedback via Feedback Hub to ensure Microsoft receives telemetry.
- For enterprise blocks: consult Windows Update for Business and Intune policies to control when components get installed, and use test rings to validate new component versions before broad deployment.
What this incremental update says about Microsoft’s on-device AI strategy
KB5079253 is modest in scope on paper, but its existence is meaningful. Microsoft’s strategy for embedding AI into Windows increasingly rests on modular, on-device components that can be updated independently of major OS releases. That gives Microsoft two advantages:- Faster iteration on model quality and performance without waiting for a large feature update cycle.
- Ability to tailor components and optimizations to specific silicon vendors and NPUs, which improves performance on Copilot+ devices.
Recommendations (for regular users and IT admins)
For most users- Let the update install automatically. The changes are incremental and aimed at quality improvements for everyday image editing.
- If you rely on Image Transform for important edits, test the feature after the update and keep a backup of originals until you’re comfortable with the output.
- Validate in a small pilot ring before broad rollout.
- Ensure driver and firmware stacks from OEMs are up to date; NPUs and GPU drivers matter for the best on-device performance.
- Monitor the Microsoft AI Components release page and support KBs for adjacent updates (Image Processing, Phi Silica, Execution Provider) because multiple AI components often land within the same servicing window.
What remains unknown and what to watch next
KB5079253’s public note is intentionally short. Microsoft does not provide internal model release notes, quantitative benchmarks, or per-silicon performance deltas in the KB itself. If you need to understand the exact improvements (for example, the classes of artifacts reduced, or latency improvements on a particular NPU), you will have to rely on:- OEM release notes for device-specific driver and firmware updates.
- Microsoft’s broader Release information for AI components page for rollout context.
Final analysis — practical takeaways
KB5079253 is a classic example of Microsoft’s new, modular on-device AI servicing approach: small, frequent, targeted component updates that refine user-facing AI features while minimizing the need for large cumulative OS updates. The update is narrowly scoped to Copilot+ PCs running Windows 11 24H2/25H2 and will install automatically once prerequisites are met; the KB replaces the earlier KB5077533 release and surfaces the new Image Transform component version in Update history. For everyday users this means slightly better generative erase-and-fill behavior in Photos and Paint; for IT operators it means this is another incremental binary to validate in your environment and to include in your managed-update plans. (support.microsoft.com)If you rely on Image Transform for production workflows, validate the update on a test device and keep a rollback/backup plan for mission-critical edits. For everyone else: update, test, and enjoy slightly smarter on-device editing — just be mindful of drivers, staged rollout, and the fact that these KBs rarely contain deep technical changelogs, so real-world testing remains the most reliable verification method.
