Overview

0X0000239D is the Win32 representation of DNS_ERROR_STANDBY_KEY_NOT_PRESENT. 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 DNS_ERROR_STANDBY_KEY_NOT_PRESENT condition
  • The calling program encountered the documented result: The specified signing key does not have a standby key to revoke.
  • A configuration, resource, or dependency used by the registry and configuration operation did not meet its requirements
  • A recent program, service, installer, or system change altered the context in which 0X0000239D occurs

Symptoms

  • Confirm which operation returned 0x0000239D
  • Match 0x0000239D to events from the same timestamp
  • Retest once and preserve any changed result

Prevention

  • Preserve Application and System events that accompany 0X0000239D
  • Use supported installers and configuration methods for the affected registry and configuration workflow
  • Document changes so the operating context for DNS_ERROR_STANDBY_KEY_NOT_PRESENT can be reconstructed

How to troubleshoot error 0X0000239D

Use these Windows-native steps in order. Stop when Windows Update works again; advanced repair commands are not necessary on every PC.

1

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.

2

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.

3

Repair 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.

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. Causes and repair steps vary by system evidence; this report does not claim a universal success rate.
