SeverityMediumSystemsWindows 10 / 11SymbolSTATUS_FLT_MUST_BE_NONPAGED_POOLUpdatedSep 1, 2026

Overview

0XC01C000C is the NTSTATUS representation of STATUS_FLT_MUST_BE_NONPAGED_POOL. 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 STATUS_FLT_MUST_BE_NONPAGED_POOL condition
  • The calling program encountered the documented result: A nonpaged pool must be used for this type of context.
  • A configuration, resource, or dependency used by the windows system operation operation did not meet its requirements
  • A recent program, service, installer, or system change altered the context in which 0XC01C000C occurs

Symptoms

  • Confirm which operation returned 0XC01C000C
  • Match 0XC01C000C to events from the same timestamp
  • Retest once and preserve any changed result

Prevention

  • Preserve Application and System events that accompany 0XC01C000C
  • Use supported installers and configuration methods for the affected windows system operation workflow
  • Document changes so the operating context for STATUS_FLT_MUST_BE_NONPAGED_POOL can be reconstructed

How to troubleshoot error 0XC01C000C

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.
