What does HRESULT 0x80242020 (WU_E_UH_APPX_INVALID_PACKAGE_VOLUME) mean?

WU_E_UH_APPX_INVALID_PACKAGE_VOLUME

What WU_E_UH_APPX_INVALID_PACKAGE_VOLUME means

WU_E_UH_APPX_INVALID_PACKAGE_VOLUME (0x80242020) is a Windows Update handler error. It means the volume selected for an AppX/MSIX package operation is not a valid AppX package volume.

Where the failure occurs

Windows Package Manager tracks the volumes on which packaged apps can be staged and installed. An update that services a packaged app must target a volume that Package Manager knows about and that is usable for AppX installation. This HRESULT therefore points to the package-volume selection or availability stage, not to the package payload itself.

What to check

• Identify the package being updated and the exact target volume or path selected for staging.
• Use Get-AppxVolume to confirm that Package Manager still knows the target volume and that the expected volume is mounted and accessible.
• If packages were moved to another drive, check whether that drive was removed, reformatted, restored, or otherwise changed since the package was registered.
• Confirm that the target volume supports AppX installation rather than assuming that any writable filesystem volume is suitable.
• Correlate the Windows Update activity with AppX deployment events so a package-volume failure is not mistaken for a signature, dependency, or package-corruption error.

Evidence to preserve

• the package family/full name and Windows Update activity or update identifier
• the target volume path and the corresponding Get-AppxVolume entry
• volume mount/availability state before the failed deployment
• the first AppX deployment HRESULT or event that precedes the Windows Update wrapper error
• recent storage changes such as moving apps, replacing a disk, restoring an image, or changing the default app volume

Recovery and verification

Restore or select a valid AppX volume using supported package-management operations, then repeat the same package update. Do not delete the package repository or reset unrelated Windows Update state until the target-volume problem has been demonstrated, because those changes can remove the evidence that identifies the invalid volume.

Verification should show that the same package is staged or updated on a volume reported by Package Manager and that the original WU_E_UH_APPX_INVALID_PACKAGE_VOLUME no longer appears. If a different AppX deployment HRESULT replaces it, diagnose that new result separately.
