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.

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.

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.

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.

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.
