Windows Event Log Analyzer
Windows Event Log Analyzer
Windows Event Log Analyzer helps you instantly understand what a Windows event log entry means, why it occurred, and what to do about it. Paste any event directly from Event Viewer, PowerShell, or your SIEM — and get a structured analysis in seconds.
Designed for system administrators and IT professionals who need fast, practical answers without searching through documentation.
Windows Event Log Analyzer
Paste any Windows Event Log entry to get an instant explanation, likely cause, and recommended fix.
How to use the Event Log Analyzer
Method 1 — Copy from Event Viewer
- Press
Win + R, typeeventvwr.msc, and press Enter to open Event Viewer. - Navigate to the log — for example Windows Logs → System or Windows Logs → Application.
- Click on any event in the list to select it.
- Right-click the event → Copy → Copy Details as Text.
- Paste the copied text into the input field above and click Analyze Event.
Method 2 — Export from PowerShell
To retrieve the most recent event from a specific log:
Get-WinEvent -LogName System -MaxEvents 1 | Format-List *
To filter by a specific Event ID — for example, Event ID 7034:
Get-WinEvent -FilterHashtable @{LogName='System'; Id=7034} -MaxEvents 1 | Format-List *
Copy the output and paste it into the analyzer above.
You can also paste event data from monitoring tools like Zabbix, Splunk, or Graylog — the analyzer accepts any text format and does not require a specific structure.
Select your preferred Response Language from the dropdown before running the analysis. The Auto-detect option will match the language of the event description automatically.
What the analyzer returns
Each analysis includes four parts:
- What happened — a plain-language summary of the event in one sentence
- Likely cause — the most common reasons this event appears in real environments
- Recommended actions — concrete steps to investigate or resolve the issue, including relevant PowerShell or CMD commands
- Severity assessment — whether the event requires immediate attention or can be addressed during normal maintenance
Understanding Windows Event Logs
Windows records system activity in three primary logs: System, Application, and Security. Each event has an Event ID that identifies the type of activity, a Source that identifies the component that generated it, and a Level that indicates severity — Information, Warning, or Error.
Event IDs are not always self-explanatory. An Event ID 7034 from Service Control Manager means a service crashed unexpectedly. An Event ID 4625 in the Security log means a failed logon attempt. Knowing what an ID means and what caused it requires either experience or research — this tool replaces that lookup with an instant analysis.
Example
Input — paste the full event text from Event Viewer:
Log Name: System
Source: Service Control Manager
Date: 3/20/2026 09:14:33 AM
Event ID: 7034
Task Category: None
Level: Error
Description:
The Print Spooler service terminated unexpectedly. It has done this 1 time(s).
Output — analysis result:
What happened:
The Windows Print Spooler service crashed unexpectedly.
Likely cause:
The service may have been terminated due to a memory error, a corrupted print
driver, or a conflicting process accessing the spooler queue.
Recommended actions:
1. Restart the service:
Restart-Service -Name Spooler
2. If the service crashes again, check for driver issues:
printui /s /t2
3. Clear the spooler queue folder:
C:\Windows\System32\spool\PRINTERS
Severity assessment:
Medium — does not affect system stability, but users will be unable to print
until the service is restored.
Common Windows Event IDs
A quick reference for the most frequently encountered Event IDs across System and Security logs.
| Event ID | Log | Level | Description |
|---|---|---|---|
| 41 | System | Critical | System rebooted without a clean shutdown |
| 1074 | System | Information | Shutdown or restart initiated by a process or user |
| 6005 | System | Information | Event log service started — indicates system boot |
| 6006 | System | Information | Event log service stopped — indicates clean shutdown |
| 6008 | System | Error | Unexpected shutdown — previous shutdown was not clean |
| 7034 | System | Error | A service terminated unexpectedly |
| 7036 | System | Information | A service entered the running or stopped state |
| 7045 | System | Information | A new service was installed |
| 4624 | Security | Audit Success | Successful account logon |
| 4625 | Security | Audit Failure | Failed account logon attempt |
| 4648 | Security | Audit | Logon attempt using explicit credentials |
| 4720 | Security | Audit | A user account was created |
| 4740 | Security | Audit | A user account was locked out |
| 4776 | Security | Audit | Domain controller validated credentials |
Paste any of these into the analyzer above to get a full explanation.
Learn more about Windows Event Logs
Any Windows event log entry — System, Application, Security, Setup, or custom application logs. The tool works with both Windows Server and Windows desktop events.
The more context you provide, the better the analysis. Pasting the full event including Event ID, Source, and Description gives the most accurate results. A partial entry with just the description also works.
AI-generated responses may vary slightly between requests. The core analysis — likely cause and recommended actions — remains consistent, but wording may differ.
The event text is sent to an AI API for analysis and is not stored on zaur.it servers. Do not paste events containing passwords, personal user data, or sensitive credentials.
Each event is assigned a severity level:
- Information — routine activity, no action required
- Warning — something unexpected occurred but the system recovered
- Error — a significant problem that may require attention
- Critical — a serious failure that requires immediate action
- Audit Success / Failure — used in the Security log for logon and access events
Windows Event Logs are stored as .evtx files in:
C:\Windows\System32\winevt\LogsThe main log files are:
System.evtx— OS and driver eventsApplication.evtx— application and service eventsSecurity.evtx— logon, access, and audit events
You can open these files directly in Event Viewer or query them with PowerShell using Get-WinEvent.
This usually means a temporary issue with the analysis service. Wait a few seconds and try again. If the problem persists, try reloading the page.
What types of events can I analyze? Any Windows event log entry — System, Application, Security, Setup, or custom application logs. The tool works with both Windows Server and Windows desktop events.
Do I need to paste the full event or just the description? The more context you provide, the better the analysis. Pasting the full event including Event ID, Source, and Description gives the most accurate results. A partial entry with just the description also works.
Why do I sometimes get different answers for the same event? AI-generated responses may vary slightly between requests. The core analysis — likely cause and recommended actions — remains consistent, but wording may differ.
Is my data sent anywhere? The event text is sent to an AI API for analysis and is not stored on zaur.it servers. Do not paste events containing passwords, personal user data, or sensitive credentials.
The analyzer returns an error. What should I do? This usually means a temporary issue with the analysis service. Wait a few seconds and try again. If the problem persists, try reloading the page.
