Windows Update Error Codes

Having issues using Windows Update? Windows Update is infamous for its cryptic error codes. This list of error codes (also known as HRESULTs) and their associated description message might help you to figure out what’s going on. With the exception of the Legacy Update errors, these are the original error messages written by Microsoft. If you can’t find an error listed here, try looking up the error code at hresult.info.

Trying to get Windows Update working on an old version of Windows? You’ll need Legacy Update.

CodeDescription
00200017A subset of the job's files transferred successfully before the IBackgroundCopyJob::Complete method was called. Those that were not complete were deleted.
0020001AUnable to delete all temporary files associated with the job.
00200055The configuration preference has been saved successfully, but the preference will not be used because a configured Group Policy setting overrides the preference.
80200001The requested job was not found.
80200002The requested action is not allowed in the current job state.
80200003The job must contain one or more files before you can resume the job.
80200004File information is not available because the error is not associated with a local or remote file.
80200005Protocol information is not available because the error is not associated with the specified transfer protocol.
8020000DThe destination file system volume, specified in the local file name, is locked.
8020000EThe destination volume, specified in the local file name, has changed. For example, the original floppy disk has been replaced with a different floppy disk.
8020000FError information is only available when the state of the job is BG_JOB_STATE_ERROR. The error information is not available after BITS begins transferring the job's data or the client exits.
80200010The network adapter is inactive or disconnected. All jobs are placed in the BG_JOB_STATE_TRANSIENT_ERROR state.
80200011The server did not return the file size. BITS only transfers static content and requires the HTTP server to return the Content-Length header. The transfer request fails if the URL points to dynamic content.
80200012The server does not support the HTTP/1.1 protocol.
80200013The server does not support the Content-Range header. Typically, you receive this error when you try to download dynamic content. You can also receive this error if an intermediate proxy is removing the Content-Range or Content-Length header.
80200014Remote use of BITS is not supported. For more information, see Users and Network Connections.
80200015The network drive mapping for the local file is different for the current owner than for the previous owner.
80200016The new owner has insufficient permissions to the temporary job files.
80200018The HTTP proxy list is too long. The list must not exceed 32 KB.
80200019The HTTP proxy bypass list is too long. The list must not exceed 32 KB.
8020001CYou cannot add more than one file to an upload job.
8020001DThe contents of the local file changed after the transfer process began. The contents of the local file cannot change after the transfer process begins on an upload or upload-reply job.
80200020The size of the upload file exceeds the maximum allowed upload size specified on the server.
80200021The specified string is too long.
80200022The client and server were unable to negotiate a protocol to use for the upload job.
80200023Scripting or execute permissions are enabled on the IIS virtual directory associated with the job. To upload files to the virtual directory, disable the scripting and execute permissions on the virtual directory.
80200025The user name cannot exceed 300 characters.
80200026The password cannot exceed 65535 characters.
80200027The specified authentication target is not valid.
80200028The specified authentication scheme is not valid.
8020002BThe specified byte range is invalid. The byte range must exist within the specified remote file.

80200047Peer-caching is disabled.
80200048The cache record is in use and cannot be changed or deleted. Try again after a few seconds.
80200049The job count for the user has exceeded the per user job limit set by the MaxJobsPerUser Group Policy setting.
80200050The job count for the computer has exceeded the per computer job limit set by the MaxJobsPerMachine Group Policy setting.
80200051The file count for the job has exceeded the per job file limit set by the MaxFilesPerJob Group Policy setting.
80200052The range count for the file has exceeded the per file range limit set by the MaxRangesPerFile Group Policy setting.
80200053The application requested data from a website, but the response was not valid. For details, use Event Viewer to view the Application Logs\Microsoft\Windows\Bits-client\Operational log.
80200054BITS timed out downloading the job. The download did not complete within the maximum download time set on the job or the MaxDownloadTime Group Policy setting.
80190190The server could not process the transfer request because the syntax of the remote file name is invalid.
80190191The user does not have permission to access the remote file. The requested resource requires user authentication.
80190194The requested URL does not exist on the server. In IIS 7, this error can indicate that BITS uploads are not enabled on the virtual directory (vdir) on the server, or that the upload size exceeds the maximum upload limit.
80190197The user does not have permission to access the proxy. The proxy requires user authentication.
8019019EThe server cannot process the transfer request. The Uniform Resource Identifier (URI) in the remote file name is longer than the server can interpret.
801901F5The server does not support the functionality required to fulfill the request. In IIS 6, this error indicates that BITS uploads are not enabled on the virtual directory (vdir) on the server.
801901F7The service is temporarily overloaded and cannot process the request. Resume the job at a later time.
801901F8The transfer request timed out while waiting for a gateway. Resume the job at a later time.
