0X0000056E
A cross-encrypted password is necessary to change this user password
Microsoft defines 0X0000056E as ERROR_LM_CROSS_ENCRYPTION_REQUIRED: A cross-encrypted password is necessary to change this user password.
Overview
0X0000056E is the Win32 representation of ERROR_LM_CROSS_ENCRYPTION_REQUIRED. The code identifies the documented condition, while the calling program, timestamp, logs, and repeatable operation identify the responsible component.
Common causes
- The affected operation returned the official ERROR_LM_CROSS_ENCRYPTION_REQUIRED condition
- The calling program encountered the documented result: A cross-encrypted password is necessary to change this user password.
- A configuration, resource, or dependency used by the security and permissions operation did not meet its requirements
- A recent program, service, installer, or system change altered the context in which 0X0000056E occurs
Symptoms
- Confirm which operation returned 0x0000056E
- Match 0x0000056E to events from the same timestamp
- Retest once and preserve any changed result
Prevention
- Preserve Application and System events that accompany 0X0000056E
- Use supported installers and configuration methods for the affected security and permissions workflow
- Document changes so the operating context for ERROR_LM_CROSS_ENCRYPTION_REQUIRED can be reconstructed

How to troubleshoot error 0X0000056E
Use these Windows-native steps in order. Stop when Windows Update works again; advanced repair commands are not necessary on every PC.
Windows Update
Retry the failed update after restarting
Restart Windows and retry the update
Save your work, restart the PC, then open Settings > Windows Update and select Check for updates. A restart can release pending files without changing Windows configuration.
Other troubleshooters
Automatically find common update problems
Run the Windows Update troubleshooter
Open Settings > System > Troubleshoot > Other troubleshooters. Locate Windows Update and select Run. Current Windows 11 versions may continue the diagnostic flow in Get Help.
DISM.exe /Online /Cleanup-Image /RestoreHealthsfc /scannowRestart Windows, then check for updatesRepair Windows components when indicated
If troubleshooting still reports missing or damaged components, open Terminal as administrator, run DISM RestoreHealth, and then run System File Checker. Do not interrupt either scan.
Before advanced repair: Back up important files. Managed work or school PCs may use organization update policies, so contact the administrator before changing services or update components.
Official-source grounding
The error meaning is grounded in Microsoft System Error Codes (WinError.h). The visual sequence also follows Microsoft Support guidance for Windows Update troubleshooting and Microsoft DISM repair guidance.
