0x00240004 is a status or completion value, not necessarily a failure. A callback was marked to be disconnected later because the request to disconnect the operation came while a callback was executing.
Completion or status value
Read the exact screen and operation before selecting a repair. This page does not run commands or collect files, keys or logs.
What this value means
A callback was marked to be disconnected later because the request to disconnect the operation came while a callback was executing.
Read this value in Windows Update, CBS or the update service context. A similar hexadecimal value in a different feature can need a different response.

Safe next steps
- For 0x00240004 (WU_S_MARKED_FOR_DISCONNECT), check whether the operation actually finished and whether the application asks for a restart or another step.
- Save work before a required restart and confirm the result in the application or Windows update history.
- Do not run a repair merely because a status value contains the word “error” in its symbolic name.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
