Several of the most-searched Windows events are harmless, and the search results for them almost universally recommend a fix. DCOM 10016 is the clearest case — Microsoft has published guidance saying it can be ignored and that editing permissions to silence it risks breaking the component. Reading whether an event matters is worth more than reading what it means.
- 10016 — DistributedCOM permission errorMicrosoft has published guidance saying these can be safely ignored, and that editing the registry and DCOM permissions to silence them — which is what almost every search result instructs — risks breaking the component instead. It is the most-searched harmless event in Windows.
- Safe to ignore
- 41 — Kernel-Power: the system rebooted without cleanly shutting downThis is a symptom with no cause attached, which is why it frustrates people: it says the machine stopped abruptly and nothing more. Power supply, overheating, failing RAM and a hard freeze all produce exactly this. Look for a 1001 BugCheck immediately before it — if there is one, the crash was a blue screen and has a stop code to work with.
- Check it
- 6008 — The previous system shutdown was unexpectedUseful only for its timestamp. Match it against what was running, and against 41 and 1001 in the same window.
- Context
- 1001 — BugCheck — a blue screen occurredThe one worth acting on. It carries the stop code, which names a cause where 41 does not. Take the code from here rather than from a photograph of the screen.
- Act on it
- 1000 — Application errorThe faulting module is what matters, not the application. A crash inside a graphics or audio driver DLL points at the driver rather than at the program that happened to call it.
- Context
- 7000 — A service failed to startCheck the service name and its dependencies. Frequent after an uninstall that left a service registered with its binary removed.
- Check it
- 7034 — A service terminated unexpectedlyA rising count on the same service is worth pursuing. A single occurrence around a reboot usually is not.
- Check it
- 51 — A paging error occurred on a diskTake this seriously and check the drive health. Paging errors frequently precede a drive failure by weeks, and they appear long before anything is visibly wrong.
- Act on it
- 153 — The IO operation was retriedOccasional retries happen on healthy systems. A pattern of them, especially alongside 51, points at the drive or its cable.
- Check it
- 2004 — Resource exhaustion detectedThe process list in the event is the useful part. It names what was consuming memory at the moment it ran out, which is otherwise very hard to reconstruct afterwards.
- Check it
- 4625 — An account failed to log onVolume is what matters. A handful is normal; hundreds from one source on a machine reachable from the internet is not.
- Context
- 129 — Reset to device issuedA serious storage signal, frequently a failing drive, a cable, or a controller driver problem. Back up before investigating.
- Act on it
What this cannot tell you
- Covers the events people actually search for rather than the thousands Windows defines. For anything else the event's own description in Event Viewer is usually more informative than a lookup.
- Event IDs are only unique within a source. The same number from a different source means something else entirely, so check the source name alongside it.
- Says whether an event is worth acting on. It cannot diagnose the underlying fault from the ID alone.
- Parsed in your browser. Nothing is uploaded, and what you paste is not stored.

How this reads your output
Each entry leads with whether the event is worth acting on, and only then with what it means — because that ordering is what is missing everywhere else. Several of the most-searched Windows events are harmless, and the search results for them almost universally recommend a fix. DCOM 10016 is the clearest case: Microsoft has published guidance saying it can be ignored and that editing DCOM permissions to silence it risks breaking the component, which is exactly what most guides instruct. Kernel-Power 41 is the opposite problem — genuinely worth investigating and carrying no cause at all, since it only records that the machine stopped abruptly.
What the results mean
- Safe to ignore
- Logged noise. Editing settings to silence these usually risks more than it fixes.
- Act on it
- Storage and crash events. 51, 129 and 1001 are the ones that name a real fault.
- 41 Kernel-Power
- Records that the machine stopped and nothing about why. Look for a 1001 immediately before it.
- Source name
- Event IDs are unique only within a source. The number alone is ambiguous.
Common problems and fixes
- Event 10016 fills my log
- Microsoft's own guidance says to ignore it. The registry and DCOM permission edits most guides recommend risk breaking the component that logged it.
- Event 41 keeps appearing and I cannot find a cause
- It does not carry one — it records that the machine stopped abruptly, after the fact. Look for a BugCheck 1001 in the same window, which does carry a stop code.
- The description in Event Viewer is more detailed than this
- Then use it. This covers the commonly searched IDs; the event's own description is frequently the better source.
Frequently asked questions
Should I fix DCOM error 10016?
No. Microsoft has published guidance saying these events can be safely ignored, and that changing DCOM permissions to stop them risks breaking the component. It is the most-searched harmless event in Windows.
Why does Kernel-Power 41 not say what went wrong?
Because it is written on the next boot, after the fact. Windows had no opportunity to record a cause. A power supply fault, overheating, failing memory and a hard freeze all produce the same event.
Are Event IDs unique?
Only within a source. The same number logged by a different source means something else, which is why a lookup by number alone can mislead.
