What is the MoAppHangXProc Error?
The MoAppHangXProc error typically appears in the Windows Event Viewer and is associated with certain Metro or Modern-style Windows applications. It usually indicates that a background process associated with a Windows Store app is no longer responding. This may happen due to corrupt apps, registry issues, or conflicts with third-party software.

Common Causes of the MoAppHangXProc Error
Understanding the root cause of this error is key to solving it. Here are several common triggers you should consider:
- Corrupted Windows Store Apps – One of the most frequent causes is a malformed or incomplete app installation.
- Operating System Glitches – Outdated or buggy Windows updates may affect how apps behave.
- Third-party Software Conflicts – Antivirus programs or optimization tools sometimes interfere with app processes.
- User Profile Corruption – A corrupted user profile might destabilize app processes and trigger this error.
