Fix: AIXHost.exe “The application is exiting and cannot service this request”

The error message from AIXHost.exe “The application is exiting and cannot service this request” is typically triggered by conflicts introduced by recent Windows updates or instability in background services tied to AI processing and indexing. This executable, AIXHost.exe, is part of Windows’ AI infrastructure. When these services malfunction, the process is terminated abruptly, causing this error.

In many cases, Windows Search indexing and related AI background processes create resource contention issues, leading to memory access errors. Less frequently, system file corruption can also cause instability in how these AI models initialize or execute.

Since this error is tied to specific Windows AI components and services, the most effective way to resolve it is to remove or disable the related processes and repair any corrupted files. The following solutions directly target these root causes.

1. Uninstall Microsoft Windows.Client.AIX package

The Windows.Client.AIX package includes Windows’ experimental AI components such as AIXHost.exe. These features are still in development and are primarily responsible for AI-based indexing, context recall, and background processing. If your hardware or drivers don’t fully support them, or if they conflict with other services, the package can cause instability and trigger this error.

By uninstalling this package, you will lose access to these experimental AI-driven features. However, the removal will not affect the core functionality of Windows, meaning your system will continue to operate normally without AIXHost.exe. This trade-off is often necessary to prevent repeated crashes.

1. Click Start, type PowerShell, right-click it, and select Run as administrator.
2. Run this command to check if the package exists:

   Get-AppxPackage *Windows.Client.AIX*

   

3. If the package is listed, uninstall it with:

   Get-AppxPackage *Windows.Client.AIX* | Remove-AppxPackage

   

4. Restart your PC to complete the removal.

2. Disable WSAIFabricSvc (AI Host Service)

The WSAIFabricSvc, also known as AI Host Service, continuously interacts with AIXHost.exe. If misconfigured, it can keep re-invoking the process unnecessarily. Disabling it stops Windows from generating repeated calls to AIXHost.exe.

1. Press Windows + R, type services.msc, and press Enter.
2. Locate WSAIFabricSvc (AI Host Service).
3. Double-click to open Properties.
4. Change Startup type to Disabled and stop the service if it’s running.
5. Click Apply and OK.

3. Stop Windows Search Service

Since Windows Search indexing often triggers AIXHost.exe calls, disabling this service can prevent it from interfering with system resources. This step is especially relevant if the error occurs while searching or indexing files.

1. Press Windows + R, type services.msc, and press Enter.
2. Locate Windows Search and open its Properties.
3. If running, click Stop.
4. Change Startup type to Disabled or Manual to prevent automatic restarts.
5. Apply the changes and restart your PC.

4. Repair System Files (SFC + DISM)

If corrupted system files are the root cause, repairing them can restore stability. The SFC (System File Checker) and DISM (Deployment Image Servicing and Management) tools can detect and fix these issues automatically.

1. Press Windows + S, type cmd.
2. Right-click Command Prompt → Run as administrator.
3. Run this command:

   DISM /Online /Cleanup-Image /RestoreHealth

   

4. Wait until the scan completes.
5. Then run:

   sfc /scannow

   

6. Restart your PC to apply the fixes.
