KB5077525 — Intel OpenVINO Execution Provider update (1.8.63.0)​

Executive summary​

• KB5077525 is a Windows Update delivered update that installs an updated Intel OpenVINO Execution Provider component (version 1.8.63.0) for the Windows ML / ONNX runtime stack on Windows 11 (24H2 and 25H2). (support.microsoft.com)
• The update “includes improvements to the OpenVINO Execution Provider AI component” for the listed Windows releases; Microsoft distributes it via Windows Update. You must have the latest cumulative update for your Windows 11 24H2 / 25H2 build before this update will be applied. (support.microsoft.com)
• Practically, this update affects workloads that use the Intel OpenVINO Execution Provider (EP) to accelerate ONNX models on Intel CPUs, Intel GPUs (integrated/discrete when supported), and Intel NPUs. Developers using ONNX Runtime + OpenVINO will typically see component-level fixes, performance or device support improvements, and compatibility updates. (support.microsoft.com)

Why this matters (technical rationale)​

Modern inference stacks frequently combine ONNX Runtime (as the model runtime/executor) with vendor-provided Execution Providers to map model ops to optimized device drivers. The Intel OpenVINO Execution Provider binds ONNX Runtime to Intel’s OpenVINO runtime and device plugins (CPU/GPU/NPU). Updates to the EP provide:

• Bug fixes and stability improvements for inference on Intel devices. (support.microsoft.com)
• Performance improvements or optimizations for specific model types (e.g., vision models and LLM inference optimizations are a common target for recent OpenVINO releases).
• Compatibility tweaks for newer drivers / OS builds so that Windows ML and ONNX-based apps continue to run reliably on modern Intel platforms. (support.microsoft.com)

Key implications for different audiences​

IT administrators (enterprise / managed devices)

• Delivery and control:
• Because Microsoft distributes KB5077525 via Windows Update, standard enterprise controls apply: Windows Update for Business, Microsoft Intune feature update policies, WSUS, and Configuration Manager (SCCM) can be used to control rollout timing and rings. If you allow automatic Windows Update, machines that meet the prerequisite will receive this update automatically; if you target updates via WSUS/SCCM/Intune, you can schedule and test. (See MS update-management guidance for your environment.) (support.microsoft.com)
• Prerequisites and staging:
• Ensure the latest cumulative update for your Windows 11 24H2/25H2 builds is installed before deploying KB5077525. Test on a representative pilot group (drivers, firmware, and apps that use Windows ML/OpenVINO). (support.microsoft.com)
• Inventory and impact analysis:
• Identify devices running workloads that use Windows ML / ONNX Runtime with the OpenVINO EP (edge inference machines, AI PCs, developer workstations). Test business-critical models with the updated EP in a lab before broad rollout to detect regressions.
• Rollout strategy:
• Pilot → targeted deployment → broad deployment. Keep rollback paths ready (see “Rollback/uninstall” below). Monitor application telemetry and Event Viewer on pilot systems after update.

Developers and data scientists

• How this affects your apps:
• If your app uses ONNX Runtime and explicitly selects the OpenVINO Execution Provider (or relies on Windows ML to route to the EP), you may see improved inference stability or performance due to bug fixes and plugin improvements. Test your most important models (image models, detection models, LLMs if using OpenVINO components) after the update.
• How to use OpenVINO EP in ONNX Runtime:
• ONNX Runtime publishes an OpenVINO Execution Provider integration and pre-built packages (for example, onnxruntime-openvino wheels for Python). If you build or package ONNX Runtime with OpenVINO EP, confirm the EP and OpenVINO runtime versions in your CI/CD to ensure compatibility.

Compatibility and versions — practical notes​

• Microsoft KB scope: KB5077525 applies specifically to Windows 11 24H2/25H2 and updates the Windows ML Runtime Intel OpenVINO Execution Provider component on those OS releases. Confirm that target machines are on those servicing channel builds before expecting the update to show. (support.microsoft.com)
• OpenVINO runtime releases: Intel publishes OpenVINO runtime releases and release notes. New runtime and toolchain versions bring model support, optimization, and bugfixes — those improvements are the upstream source for EP changes. Use the Intel release notes to see specific runtime fixes and features (for example, Unicode path fixes, LLM/CPU/GPU performance improvements, and profiling support described in recent OpenVINO release notes).
• ONNX Runtime compatibility: ONNX Runtime’s OpenVINO Execution Provider expects a compatible set of OpenVINO runtime components. ONNX Runtime documentation lists compatibility guidelines (which EP versions are compatible with which OpenVINO releases and ONNX Runtime releases). If you package ONNX Runtime with a pinned set of EP/OpenVINO libraries, check those compatibility tables during upgrades.

How to check that KB5077525 is installed​

• Settings (GUI)
• Go to Settings → Windows Update → Update history. The KB entry should appear as “Windows ML Runtime Intel OpenVINO Execution Provider (KB5077525)”. (support.microsoft.com)
• Control Panel (classic)
• Control Panel → Programs and Features → View installed updates. Search the list for KB5077525.
• PowerShell (example)
• You can query installed updates from PowerShell; a simple check (may vary by environment/what source recorded the update):
• Get-HotFix -Id KB5077525 (Note: Get-HotFix output can vary based on how the update was applied and which catalog recorded it.)
• If you use enterprise update management (WSUS/ConfigMgr/Intune), also check the management dashboard for KB5077525 compliance.
• Windows Update log / Event Viewer
• If an update failed, Windows Update logs and the System event log will provide failure codes and diagnostics.

How to install / how the update is delivered​

• Microsoft’s KB states this update is delivered via Windows Update and will be installed automatically on machines meeting prerequisites. For managed environments, use WSUS, Configuration Manager, or Intune to stage/approve the update across rings instead of letting it auto-install immediately. (support.microsoft.com)

Replacement and history​

• KB5077525 replaces a previously released update KB5072094. If you previously had KB5072094 installed, KB5077525 may supersede it. The KB page lists replacement information. (support.microsoft.com)

Developer guidance: testing, packaging, and runtime usage​

• If you embed the OpenVINO EP into your ONNX Runtime-based product:
• Pin and test the exact EP/OpenVINO runtime versions you ship. Microsoft’s KB updates the Windows ML Runtime component that Windows may use; if you supply your own ONNX Runtime bundle with a different OpenVINO runtime, test for ABI/API compatibility across versions.
• If you rely on system-provided OpenVINO/Windows ML routing:
• The OS-provided update (KB5077525) updates system components that may be used by Windows ML and by ONNX Runtime/EP when configured to use system libraries — test end-to-end to ensure the app uses the expected EP instance.
• Installing ONNX Runtime OpenVINO EP for Python:
• ONNX Runtime docs point to onnxruntime-openvino wheels and guidance for using the EP from Python or C++ code. Confirm which ONNX Runtime version + OpenVINO combination you need and install the appropriate pre-built packages or build from source if you require customizations.

Performance testing and validation checklist​

When validating the update, follow this checklist:

• Representative test set:
• Use the same models and input data your application uses in production (image sizes, batch sizes, token lengths for LLMs, etc.).
• Baseline measurements:
• Record baseline latency/throughput and memory usage before applying KB5077525.
• Run after update:
• Measure latency, throughput, and memory again after the update on the same hardware and OS patch level.
• Verify device mapping:
• Confirm models are running on the intended device (CPU/GPU/NPU) and check whether the EP chooses different kernels or fallback paths post-update.
• Profile and trace:
• Use OpenVINO profiling (for example, enabling profiling where supported) and ONNX Runtime perf counters to find regressions or unexpected behavior. Recent OpenVINO updates highlight additions such as profiling support and tokenization/LLM improvements — use the runtime release notes to learn how to enable and interpret profiling outputs.
• Validate functional correctness:
• Check outputs for numerical differences within acceptable tolerance (floating-point variability may change slightly after optimizations).

Troubleshooting: common steps​

If you see post‑update problems (application crashes, worse performance, model failures), try:

• Confirm the update is installed
• Use Settings → Windows Update → Update history. (support.microsoft.com)
• Check application logs and Windows Event Viewer
• Look for clr/Win32 errors, driver errors, or OpenVINO/ONNX runtime logs.
• Reproduce on a clean/test machine
• Reproduce the issue in a lab machine with identical OS/driver versions and the updated EP.
• Driver updates
• Make sure the latest Intel device drivers (GPU/NPU) and firmware are installed if your model runs on GPU or NPU — driver mismatches commonly cause runtime failures.
• Reinstall or roll back
• Uninstall KB5077525 (see next section) or roll back to a previous image to see whether behavior returns to baseline.
• Check OpenVINO/ONNX Runtime compatibility
• If you bundle your own ONNX Runtime & OpenVINO libraries, an OS-level EP update can sometimes expose ABI or behavior differences — verify the exact binaries used at runtime.
• Contact channels
• Microsoft Support (for Windows update-specific issues) and Intel / OpenVINO channels (for runtime/EP behavior) — collect logs, model samples, and reproducible testcases before opening a ticket.

Rollback / uninstall options​

• Uninstall via Settings or Control Panel:
• If necessary, the update can be removed through Settings → Windows Update → Update history → Uninstall updates (or Control Panel → Programs and Features → View installed updates). After uninstall, reboot as required.
• Restore from image:
• For managed systems, restoring a pre-update image or reimaging may be used for quicker rollback across many devices.
• Restore points:
• If a system restore point is available from before the update, the restore can be attempted, recognizing that system restore will affect other system changes as well.
• Note: enterprise environments using WSUS/ConfigMgr should follow their standard rollback process and update-approval workflows.

Security and privacy considerations​

• KB5077525 is an update to runtime/EP components (non‑significant attack-surface components in many scenarios), but as with all runtime updates: test applications for regressions and monitor for new telemetry or logging behavior. Use the standard corporate change-control and testing practices before wide deployment. (support.microsoft.com)

FAQ (short)​

Q — Do I need to do anything if my devices are set to automatic Windows Update?
A — No action required in many cases: Microsoft will automatically push KB5077525 to applicable Windows 11 24H2/25H2 machines that have the required cumulative update installed. Still, for production or managed fleets you should pilot and validate before broad rollout. (support.microsoft.com)
Q — Will this update change my on‑device OpenVINO version for apps that bundle their own OpenVINO runtime?
A — Not necessarily. If your app bundles its own OpenVINO and ONNX Runtime libraries, it will typically use those bundled libs. The KB updates the system Windows ML/OpenVINO components that system-level callers and OS-integrated pathways use. Test both system-provided and app-bundled scenarios.
Q — Where can I get the OpenVINO EP packages for ONNX Runtime if I need to rebuild or package?
A — ONNX Runtime docs list the prebuilt OpenVINO EP packages/wheels and guidance for building from source; use those packages if you need a self-contained runtime.

Practical next steps (recommended checklist)​

For IT admins:

• Identify machines running Windows 11 24H2/25H2 that host AI workloads using the OpenVINO EP.
• Ensure the latest cumulative updates for those Windows releases are installed (prereq for KB5077525). (support.microsoft.com)
• Create a pilot ring with representative hardware (CPU-only, integrated GPU, discrete GPU, NPU where applicable) and install KB5077525. Run function + performance tests.
• Monitor logs, perf, and application correctness; if OK, gradually expand the ring. Use management tools (WSUS/ConfigMgr/Intune) to stage rollout.
• Document rollback procedures (how to uninstall the update, restore images).

For developers:

• Re-run your CI test matrix (models, quantized vs FP32/FP16, device variants) against the updated EP.
• If you ship an ONNX Runtime + EP bundle, consider pinning and testing exact EP/OpenVINO runtime binaries you intend to deliver.
• Use OpenVINO/ONNXRuntime profiling and Intel release-note guidance for performance tuning; test LLM-style and vision model workloads if you use them (OpenVINO updates often include LLM and performance fixes).
