frequent error message

Question

How can I correct this message

C:\windows\SystemApps\MicrosoftWindows.Client.AIX_cw5n12txyewy\AIXHost.exe

Answer 1

Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

This error means that the application is exiting. This occurs when there are corrupted system files on the PC. To sort out the issue, kindly follow the steps below:

Method 1. Reinstall AIXHost.exe

 

Open Terminal (Admin) or Windows PowerShell(Admin) (Press Windows key + X then click Terminal(Admin))

Copy, paste, and enter each command below:

Get-AppxPackage MicrosoftWindows.Client.AIX | Remove-AppxPackage

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

If none of the above solutions work, I suggest doing an in-place upgrade, which will update the device to the latest version and repair all issues without deleting any files.

The message refers to a built‑in Windows 11 system app component (AIXHost.exe) under C:\Windows\SystemApps. When such system apps show frequent errors, it is usually due to a damaged or inconsistent app package rather than a virus.

On Windows 10/11, built‑in apps that use the MSIX app package format can show repeated errors or fail to open after system changes such as restore points or updates. Typical symptoms include “This app can’t open”, apps not responding, or crashes when starting.

To correct recurring errors with this system app, use these steps in order:

1. Try opening the app again
   • If the error appears only once and the app works on the second attempt, no further action may be needed. This behavior is documented for MSIX‑packaged apps after system changes.
2. Repair or reinstall the app from Microsoft Store (if exposed there)
   • Open Microsoft Store.
   • Search for the related Windows component (for example, if it is tied to a specific Windows feature or app) and choose Repair or Reinstall if available.
3. Reinstall from original source
   • For built‑in Windows components, this typically means using Windows features or optional features to remove and re‑add the feature that uses AIXHost.exe, if it is listed.
4. Run Windows Update
   • Go to Settings → Windows Update.
   • Check for updates and install all available quality and app updates.
   • Restart the PC after updates complete.
5. Repair apps and programs more generally
   • Follow the guidance in the Windows “Repair apps and programs” article to repair affected apps if they appear in Settings → Apps → Installed apps.

If the error persists after these steps, collect the exact error text that appears with AIXHost.exe and check for any recent System Restore or major system changes, as those are known triggers for MSIX app issues.
