Windows.Clien.AIX_cw5nih2tewy\AIXHost.exe error

[JoSlc]

Hi All,

Does anyone in the community know what the cause of this error is?

C:\Windows\SystemApps\Microsoft\Windows.Clien.AIX_cw5nih2tewy\AIXHost.exe error

I just purchased this Omnibook less than 3 weeks ago but just encountered this error today. Not sure what caused it. I've been very careful about downloading and installing and making sure I don't do it for all unknown s/w and websites. Does anyone know how to resolve this issue? 

Thanks in advance!

Hi @JoSlc,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

The error you’re seeing: C:\Windows\SystemApps\Microsoft.Windows.Client.AIX_cw5n1h2txyewy\AIXHost.exe. is related to Windows Copilot / AI features introduced in recent Windows builds (including 23H2 and 24H2 onward). The AIXHost.exe process belongs to Microsoft’s AI Experience Host, which powers Copilot and some AI-driven UI elements. When this crashes, it usually indicates:

Recommended Fix Steps

1. Run System File Checker & DISM

• Open Command Prompt (Admin): sfc /scannow
                               DISM /Online /Cleanup-Image /RestoreHealth
• This repairs corrupted system files.

2. Check Windows Updates

• Go to Settings > Windows Update → Install all updates.
• Especially Optional Updates (drivers and feature packs).

3. Repair or Reset AI Experience Pack

• Open Settings > Apps > Installed Apps.
• Search for Microsoft AI Experience Pack.
• Click Advanced Options → Repair or Reset.

4. Update Graphics Drivers

• Use HP Support Assistant or HP’s driver page for your OMEN model: Official HP® Support.
• AI features rely on GPU acceleration; outdated drivers can cause crashes.

5. Check Reliability Monitor

• Press Win + R, type perfmon /rel.
• Look for AIXHost.exe failures and note the faulting module (often a DLL).

6. Optional: Disable Copilot Temporarily

• If the error persists and you don’t use Copilot: 
• Settings > Personalization > Taskbar > Copilot → Turn off.

I hope this helps.

Take care and have an amazing day!
