WU_S_UH_INSTALLSTILLPENDING
WU_S_UH_INSTALLSTILLPENDING (0x00242015) is a Windows Update Agent success/status code meaning that the installation operation for the update is still in progress. It does not report that installation failed.
How to handle the status
- Keep the update identity and the installation operation that returned this status; do not start a second installation merely because the first call has not reached a final result.
- Wait for the existing installation to complete and then read its final result before deciding whether retry or remediation is needed.
- If progress appears stuck, correlate Windows Update logs and servicing events with the same update and time window rather than converting this status into an arbitrary failure.
What to distinguish
This status is different from an HRESULT whose high bit marks failure. It says that completion is pending, so the next useful evidence is the final installation result, reboot requirement, or a later specific Windows Update error.
