    안녕하세요**Kenneth Andersson,**

    오류 코드 0x800f081f는 Windows Update에서 필요한 구성 요소 파일을 찾을 수 없을 때 발생하는 일반적인 문제입니다. 먼저 시스템에 .NET Framework 3.5 기능이 설치되어 있는지 확인하십시오. 설치되어 있지 않으면 업데이트 프로세스가 실패할 수 있으며, 다음 명령을 사용하여 수동으로 설치할 수 있습니다. DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs /LimitAccess. 여기서 D:\sources\sxs는 Windows 설치 미디어의 실제 경로로 바꿔야 합니다. 또한 Windows Update 서비스가 제대로 실행 중인지 확인하고 %windir%\SoftwareDistribution 폴더를 재설정한 후 다시 업데이트를 시도해 보십시오.

    위의 단계를 수행한 후에도 동일한 오류가 계속 발생하면 CBS 로그(%windir%\Logs\CBS\CBS.log)를 검토하여 어떤 패키지가 문제를 일으키는지 확인하십시오. 특정 누적 업데이트와 관련된 문제라면, 가장 확실한 방법은 Microsoft 업데이트 카탈로그에서 해당 KB 업데이트를 수동으로 다운로드하여 설치하는 것입니다.

    Error 0x800f081f indicates that Windows Update cannot find the required source files to complete the update or feature installation.

    For Windows Server 2019, use the following approach:

    1. Identify the problematic update
      • Reproduce the issue by trying to install the update again so that the latest details are written to C:\Windows\Logs\CBS\CBS.log.
      • Review CBS.log to identify the specific KB/package that is failing.
    2. Download the required update package
      • Go to the appropriate update history page for your OS version (for Windows Server 2019, use the Windows 10, version 1809 and Windows Server 2019 update history) and locate the KB number of the problematic update.
      • Open Microsoft Update Catalog and search for that KB number.
      • Download the correct package for Windows Server 2019 and the correct architecture (x64) to C:\temp.
    3. Expand the .msu and locate the .cab
      • Open an elevated Command Prompt and run: 
             cd \
     cd temp
     expand -F:* windows10.0-kb4462937-x64_9e250691ae6d00cdf677707e83435a612c3264ea.msu C:\temp
        Replace the file name with the actual .msu file that was downloaded.
      • In C:\temp, locate the .cab file in the format: 
             windows10.0-KBxxxxxxx-x64.cab
    4. Repair the package (if it is partially installed)
      • If CBS/logs indicate the update is installed but corrupted, first remove and then re-add the package: 
             Dism /online /remove-package /packagepath:C:\temp\windows10.0-kb4462937-x64.cab
        (substitute the actual .cab name)
      • Restart the server if prompted.
      • Then reinstall the package: 
             Dism /online /add-package /packagepath:C:\temp\windows10.0-kb4462937-x64.cab
      • Restart the server and run Windows Update again.
    5. If the update is not installed at all
      • Skip the remove step and directly add the package with DISM: 
             Dism /online /add-package /packagepath:C:\temp\windows10.0-kb4462937-x64.cab
      • Restart and retry Windows Update.
    6. If issues persist
      • For persistent store corruption or repeated 0x800f081f/0x800f0831-type errors that are not resolved by the above steps, an in-place upgrade/repair install of the OS may be required to restore component store integrity.
