When Windows Setup fails, the result and extend code are recorded as an informational event in the Application log by Windows Error Reporting as event 1001. The event name is WinSetupDiag02. You can use Event Viewer to review this event, or you can use Windows PowerShell.
To use Windows PowerShell, type the following commands from an elevated Windows PowerShell prompt:
$events = Get-WinEvent -FilterHashtable @{LogName="Application";ID="1001";Data="WinSetupDiag02"}
$event = [xml]$events[0].ToXml()
$event.Event.EventData.Data
To use Event Viewer:
- Open Event Viewer and navigate to Windows Logs\Application.
- Click Find, and then search for winsetupdiag02.
- Double-click the event that is highlighted.
Note: For legacy operating systems, the Event Name was WinSetupDiag01.
Ten parameters are listed in the event:
| P1: The Setup Scenario (1=Media,5=WindowsUpdate,7=Media Creation Tool) |
| P2: Setup Mode (x=default,1=Downlevel,5=Rollback) |
| P3: New OS Architecture (x=default,0=X86,9=AMD64) |
| P4: Install Result (x=default,0=Success,1=Failure,2=Cancel,3=Blocked) |
| P5: Result Error Code (Ex: 0xc1900101) |
| P6: Extend Error Code (Ex: 0x20017) |
| P7: Source OS build (Ex: 9600) |
| P8: Source OS branch (not typically available) |
| P9: New OS build (Ex: 16299} |
| P10: New OS branch (Ex: rs3_release} |
The event will also contain links to log files that can be used to perform a detailed diagnosis of the error. An example of this event from a successful upgrade is shown below.
