- Windows 10
This is a 400 level topic (advanced).
See Resolve Windows 10 upgrade errors for a full list of topics in this article.
Several log files are created during each phase of the upgrade process. These log files are essential for troubleshooting upgrade problems. By default, the folders that contain these log files are hidden on the upgrade target computer. To view the log files, configure Windows Explorer to view hidden items, or use a tool to automatically gather these logs. The most useful log is setupact.log. The log files are located in a different folder depending on the Windows Setup phase. Recall that you can determine the phase from the extend code.
Note: Also see the Windows Error Reporting section in this document for help locating error codes and log files.
The following table describes some log files and how to use them for troubleshooting purposes:
|Log file||Phase: Location||Description||When to use|
|Contains information about setup actions during the downlevel phase.||All down-level failures and starting point for rollback investigations.
This is the most important log for diagnosing setup issues.
|Contains information about actions during the OOBE phase.||Investigating rollbacks that failed during OOBE phase and operations – 0x4001C, 0x4001D, 0x4001E, 0x4001F.|
|Contains information about actions during rollback.||Investigating generic rollbacks - 0xC1900101.|
|Pre-initialization (prior to downlevel):|
|Contains information about initializing setup.||If setup fails to launch.|
|Post-upgrade (after OOBE):|
|Contains information about setup actions during the installation.||Investigate post-upgrade related issues.|
|setuperr.log||Same as setupact.log||Contains information about setup errors during the installation.||Review all errors encountered during the installation phase.|
|miglog.xml||Post-upgrade (after OOBE):|
|Contains information about what was migrated during the installation.||Identify post upgrade data migration issues.|
|Contains information communication between setup.exe and Windows Update.||Use during WSUS and WU down-level failures or for 0xC1900107.|
|Supplemental rollback logs:
Event logs (*.evtx)
|$Windows.~BT\Sources\Rollback||Additional logs collected during rollback.||
Setupmem.dmp: If OS bugchecks during upgrade, setup will attempt to extract a mini-dump.
Setupapi: Device install issues - 0x30018
Event logs: Generic rollbacks (0xC1900101) or unexpected reboots.
Log entry structure
A setupact.log or setuperr.log entry (files are located at C:\Windows) includes the following elements:
- The date and time - 2016-09-08 09:20:05.
- The log level - Info, Warning, Error, Fatal Error.
- The logging component - CONX, MOUPG, PANTHR, SP, IBSLIB, MIG, DISM, CSI, CBS.
- The logging components SP (setup platform), MIG (migration engine), and CONX (compatibility information) are particularly useful for troubleshooting Windows Setup errors.
- The message - Operation completed successfully.
See the following example:
|2016-09-08 09:23:50,||Warning||MIG||Could not replace object C:\Users\name\Cookies. Target Object cannot be removed.|
Analyze log files
To analyze Windows Setup log files:
- Determine the Windows Setup error code. This code should be returned by Windows Setup if it is not successful with the upgrade process.
- Based on the extend code portion of the error code, determine the type and location of a log files to investigate.
- Open the log file in a text editor, such as notepad.
- Using the result code portion of the Windows Setup error code, search for the result code in the file and find the last occurrence of the code. Alternatively search for the "abort" and abandoning" text strings described in step 7 below.
- To find the last occurrence of the result code:
- Scroll to the bottom of the file and click after the last character.
- Click Edit.
- Click Find.
- Type the result code.
- Under Direction select Up.
- Click Find Next.
- Shell application requested abort
- Abandoning apply due to error for object
For example, assume that the error code for an error is 0x8007042B - 0x2000D. Searching for "8007042B" reveals the following content from the setuperr.log file:
Some lines in the text below are shortened to enhance readability. The date and time at the start of each line (ex: 2016-10-05 15:27:08) is shortened to minutes and seconds, and the certificate file name which is a long text string is shortened to just "CN."
27:08, Error SP Error READ, 0x00000570 while gathering/applying object: File, C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 [CN]. Will return 0[gle=0x00000570] 27:08, Error MIG Error 1392 while gathering object C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 [CN]. Shell application requested abort![gle=0x00000570] 27:08, Error Gather failed. Last error: 0x00000000 27:08, Error SP SPDoFrameworkGather: Gather operation failed. Error: 0x0000002C 27:09, Error SP CMigrateFramework: Gather framework failed. Status: 44 27:09, Error SP Operation failed: Migrate framework (Full). Error: 0x8007042B[gle=0x000000b7] 27:09, Error SP Operation execution failed: 13. hr = 0x8007042B[gle=0x000000b7] 27:09, Error SP CSetupPlatformPrivate::Execute: Execution of operations queue failed, abandoning. Error: 0x8007042B[gle=0x000000b7]
The first line indicates there was an error 0x00000570 with the file C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 [CN] (shown below):
27:08, Error SP Error READ, 0x00000570 while gathering/applying object: File, C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 [CN]. Will return 0[gle=0x00000570]
The error 0x00000570 is a Win32 error code corresponding to: ERROR_FILE_CORRUPT: The file or directory is corrupted and unreadable.
Therefore, Windows Setup failed because it was not able to migrate the corrupt file C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18[CN]. This file is a local system certificate and can be safely deleted. Searching the setupact.log file for additional details, the phrase "Shell application requested abort" is found in a location with the same timestamp as the lines in setuperr.log. This confirms our suspicion that this file is the cause of the upgrade failure:
27:00, Info Gather started at 10/5/2016 23:27:00 27:00, Info [0x080489] MIG Setting system object filter context (System) 27:00, Info [0x0803e5] MIG Not unmapping HKCU\Software\Classes; it is not mapped 27:00, Info [0x0803e5] MIG Not unmapping HKCU; it is not mapped 27:00, Info SP ExecuteProgress: Elapsed events:1 of 4, Percent: 12 27:00, Info [0x0802c6] MIG Processing GATHER for migration unit: <System>\UpgradeFramework (CMXEAgent) 27:08, Error SP Error READ, 0x00000570 while gathering/applying object: File, C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 [CN].

This analysis indicates that the Windows upgrade error can be resolved by deleting the C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18[CN] file. Note: In this example, the full, unshortened file name is C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18\be8228fb2d3cb6c6b0ccd9ad51b320b4_a43d512c-69f2-42de-aef9-7a88fabdaa3f.
