The Windows 10 upgrade process
The Windows Setup application is used to upgrade a computer to Windows 10, or to perform a clean installation. Windows Setup starts and restarts the computer, gathers information, copies files, and creates or adjusts configuration settings. When performing an operating system upgrade, Windows Setup uses the following phases:
- Downlevel phase: The downlevel phase is run within the previous operating system. Installation components are gathered.
- Safe OS phase: A recovery partition is configured and updates are installed. An OS rollback is prepared if needed. - Example error codes: 0x2000C, 0x20017
- First boot phase: Initial settings are applied. - Example error codes: 0x30018, 0x3000D
- Second boot phase: Final settings are applied. This is also called the OOBE boot phase. - Example error: 0x4000D, 0x40017
- Uninstall phase: This phase occurs if upgrade is unsuccessful. - Example error: 0x50000
Figure 1: Phases of a successful Windows 10 upgrade (uninstall is not shown):
DU = Driver/device updates.
OOBE = Out of box experience.
WIM = Windows image (Microsoft)
Quick fixes
The following steps can resolve many Windows upgrade problems.
- Remove nonessential external hardware, such as docks and USB devices.
- Check all hard drives for errors and attempt repairs. To automatically repair hard drives, open an elevated command prompt, switch to the drive you wish to repair, and type the following command. You will be required to reboot the computer if the hard drive being repaired is also the system drive.
- chkdsk /F
- Attept to restore and repair system files by typing the following commands at an elevated command prompt. It may take several minutes for the command operations to be completed. For more information, see [Repair a Windows Image](https://msdn.microsoft.com/windows/hardware/commercialize/manufacture/desktop/repair-a-windows-image).
- DISM.exe /Online /Cleanup-image /Restorehealth
- sfc /scannow
- Update Windows so that all available recommended updates are installed.
- Uninstall non-Microsoft antivirus software.
- Use Windows Defender for protection during the upgrade.
- Verify compatibility information and re-install antivirus applications after the upgrade.
- Uninstall all nonessential software.
- Update firmware and drivers.
- Ensure that "Download and install updates (recommended)" is accepted at the start of the upgrade process.
- Verify at least 16 GB of free space is available to upgrade a 32-bit OS, or 20 GB for a 64-bit OS.
Upgrade error codes
If the upgrade process is not successful, Windows Setup will return two codes:
- A result code: The result code corresponds to a specific Win32 error.
- An extend code: The extend code contains information about both the phase in which an error occurred, and the operation that was being performed when the error occurred.
For example, a result code of 0xC1900101 with an extend code of 0x4000D will be returned as: 0xC1900101 - 0x4000D.
Note: If only a result code is returned, this can be because a tool is being used that was not able to capture the extend code. For example, if you are using the Windows 10 Upgrade Assistant then only a result code might be returned.
Result codes
A result code of 0xC1900101 is generic and indicates that a rollback occurred. In most cases, the cause is a driver compatibility issue.
To troubleshoot a failed upgrade that has returned a result code of 0xC1900101, analyze the extend code to determine the Windows Setup phase, and see the Resolution procedures section later in this topic.
Result codes can be matched to the type of error encountered. To match a result code to an error:
- Identify the error code type, either Win32 or NTSTATUS, using the first hexidecimal digit:
8 = Win32 error code (ex: 0x80070070)
C = NTSTATUS value (ex: 0xC1900107) - Write down the last 4 digits of the error code (ex: 0x80070070 = 0070). These digits correspond to the last 16 bits of the HRESULT or the NTSTATUS structure.
- Based on the type of error code determined in the first step, match the 4 digits derived from the second step to either a Win32 error code, or an NTSTATUS value.
For example:
- 0x80070070 = Win32 = 0070 = 0x00000070 = ERROR_DISK_FULL
- 0xC1900107 = NTSTATUS = 0107 = 0x00000107 = STATUS_SOME_NOT_MAPPED
Some result codes are self-explanatory, whereas others are more generic and require further analysis. In the examples shown above, ERROR_DISK_FULL indicates that the hard drive is full and additional room is needed to complete Windows upgrade. The message STATUS_SOME_NOT_MAPPED is more ambiguous, and means that an action is pending. In this case, the action pending is often the cleanup operation from a previous installation attempt, which can be resolved with a system reboot.
Extend codes
Important: Extend codes reflect the current Windows 10 upgrade process, and might change in future releases of Windows 10. The codes discussed in this section apply to Windows 10 version 1607, also known as the Anniversary Update.
Extend codes can be matched to the phase and operation when an error occurred. To match an extend code to the phase and operation:
- Use the first digit to identify the phase (ex: 0x4000D = 4).
- Use the last two digits to identify the operation (ex: 0x4000D = 0D).
- Match the phase and operation to values in the tables provided below.
The following tables provide the corresponding phase and operation for values of an extend code:
| Extend code: phase | |
| Hex | Phase |
| 0 | SP_EXECUTION_UNKNOWN |
| 1 | SP_EXECUTION_DOWNLEVEL |
| 2 | SP_EXECUTION_SAFE_OS |
| 3 | SP_EXECUTION_FIRST_BOOT |
| 4 | SP_EXECUTION_OOBE_BOOT |
| 5 | SP_EXECUTION_UNINSTALL |
| Extend code: operation | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
For example: An extend code of 0x4000D, represents a problem during phase 4 (0x4) with data migration (000D).
Log files
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.
The following table describes some log files and how to use them for troubleshooting purposes:
| Log file | Phase: Location | Description | When to use |
| setupact.log | Down-Level: $Windows.~BT\Sources\Panther | 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. |
| OOBE: $Windows.~BT\Sources\Panther\UnattendGC | Contains information about actions during the OOBE phase. | Investigating rollbacks that failed during OOBE phase and operations – 0x4001C, 0x4001D, 0x4001E, 0x4001F. | |
| Rollback: $Windows.~BT\Sources\Rollback | Contains information about actions during rollback. | Investigating generic rollbacks - 0xC1900101. | |
| Pre-initialization (prior to downlevel): Windows | Contains information about initializing setup. | If setup fails to launch. | |
| Post-upgrade (after OOBE): Windows\Panther | 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): Windows\Panther | Contains information about what was migrated during the installation. | Identify post upgrade data migration issues. |
| BlueBox.log | Down-Level: Windows\Logs\Mosetup | Contains information communication between setup.exe and Windows Update. | Use during WSUS and WU down-level failures or for 0xC1900107. |
| Supplemental rollback logs: Setupmem.dmp setupapi.dev.log 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 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:
| Date/Time | Log level | Component | Message |
|---|---|---|---|
| 2016-09-08 09:23:50, | Warning | MIG | Could not replace object C:\Users\name\Cookies. Target Object cannot be removed. |
Analyze log files
The following instructions are meant for IT professionals. Also see the Upgrade error codes section in this guide to familiarize yourself with result codes and extend codes.
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](#extend-codes) portion of the error code, determine the type and location of a [log files](#log-files) to investigate.
- Open the log file in a text editor, such as notepad.
- Using the [result code](#result-codes) 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**.
- When you have located the last occurrence of the result code, scroll up a few lines from this location in the file and review the processes that failed just prior to generating the result code.
- Search for the following important text strings:
- Shell application requested abort
- Abandoning apply due to error for object
- Decode Win32 errors that appear in this section.
- Write down the timestamp for the observed errors in this section.
- Search other log files for additional information matching these timestamps or errors.
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."
setuperr.log content:
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:
setupact.log content:
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: \UpgradeFramework (CMXEAgent) 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, Info SP ExecuteProgress: Elapsed events:2 of 4, Percent: 25 27:08, Info SP ExecuteProgress: Elapsed events:3 of 4, Percent: 37 27:08, Info [0x080489] MIG Setting system object filter context (System) 27:08, Info [0x0803e5] MIG Not unmapping HKCU\Software\Classes; it is not mapped 27:08, Info [0x0803e5] MIG Not unmapping HKCU; it is not mapped 27:08, Info MIG COutOfProcPluginFactory::FreeSurrogateHost: Shutdown in progress. 27:08, Info MIG COutOfProcPluginFactory::LaunchSurrogateHost::CommandLine: -shortened- 27:08, Info MIG COutOfProcPluginFactory::LaunchSurrogateHost: Successfully launched host and got control object. 27:08, Error Gather failed. Last error: 0x00000000 27:08, Info Gather ended at 10/5/2016 23:27:08 with result 44 27:08, Info Leaving MigGather method 27:08, Error SP SPDoFrameworkGather: Gather operation failed. Error: 0x0000002C
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.
Resolution procedures
0xC1900101
A frequently observed result code is 0xC1900101. This result code can be thrown at any stage of the upgrade process, with the exception of the downlevel phase. 0xC1900101 is a generic rollback code, and usually indicates that an incompatible driver is present. The incompatible driver can cause blue screens, system hangs, and unexpected reboots. Analysis of supplemental log files is often helpful, such as:
- The minidump file: $Windows.~bt\Sources\Rollback\setupmem.dmp,
- Event logs: $Windows.~bt\Sources\Rollback*.evtx
- The device install log: $Windows.~bt\Sources\Rollback\setupapi\setupapi.dev.log
The device install log is particularly helpful if rollback occurs during the sysprep operation (extend code 0x30018). To resolve a rollback due to driver conflicts, try running setup using a minimal set of drivers and startup programs by performing a clean boot before initiating the upgrade process.

Note: If your device allows it, you can use an external USB drive for the upgrade process. Windows setup will back up the previous version of Windows to a USB external drive. The external drive must be at least 8GB (16GB is recommended). The external drive should be formatted using NTFS. Drives that are formatted in FAT32 may run into errors due to FAT32 file size limitations. USB drives are preferred over SD cards because drivers for SD cards are not migrated if the device does not support Connected Standby. |
