Answer 2

Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

This issue occurred due to a miscalibration on the Windows update. For us to sort out the problem, kindly follow the steps below:

Reset Windows update components:

Open Terminal (Admin) or Windows PowerShell with Admin(Press Windows key + X, then click Terminal (Admin))

Copy each line of command, then press Enter (one line at a time)

net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q
regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll
netsh winsock reset
netsh winsock reset proxy
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc

-Once done, restart the device and check.

If none of the above solutions work, I suggest doing an in-place upgrade, which updates the device to the latest version and fixes all issues without deleting any files.

Answer 3

Error 0x800f0983 is a generic Windows Update installation failure. For KB5077181 on Windows 11, use the following steps to work around it using only supported methods from the update documentation and general Windows Update repair guidance in the context.

1. Run component cleanup
   1. Select Start and type cmd.
   2. Right‑click Command Prompt and select Run as administrator.
   3. If prompted by UAC, select Yes.
   4. Run:

            dism /online /cleanup-image /startcomponentcleanup
      

   5. Wait for the command to complete.
   6. Restart the device.
   7. Try installing KB5077181 again from Windows Update.
2. Install KB5077181 manually via Microsoft Update Catalog If Windows Update still fails, install the update using the standalone packages:
   1. Go to the Microsoft Update Catalog page for KB5077181: https://www.catalog.update.microsoft.com/Search.aspx?q=KB5077181.
   2. Download the MSU file(s) for the correct Windows 11 edition/architecture.
   Then install using one of these methods. Method A – Let DISM handle prerequisites (recommended)
   1. Create a folder, for example C:\packages.
   2. Copy all downloaded MSU files for KB5077181 into that folder.
   3. Open an elevated Command Prompt and run (adjust path/file name as needed):

            DISM /Online /Add-Package /PackagePath:C:\packages\Windows11.0-KB5077181-x64.msu
      

      or from elevated PowerShell:

            Add-WindowsPackage -Online -PackagePath "C:\packages\Windows11.0-KB5077181-x64.msu"
      

   4. Restart when prompted.
   Method B – Install each MSU in the documented order If using individual installation, install in this exact order (using either DISM or Windows Update Standalone Installer):
   1. windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu
   2. windows11.0-kb5077181-x64_33d38563662e659ceb84fb8b65aa05ce5876f5a4.msu
   After both install successfully, restart the device.
3. Use DISM to remove and re‑add the package (advanced) If the update partially installed and is stuck, remove the LCU package and then reinstall it:
   1. Open an elevated Command Prompt.
   2. List installed packages and locate the KB5077181 package name:

            DISM /online /get-packages
      

   3. Use the exact package identity from the output with Remove‑Package, for example:

            DISM /online /Remove-Package /PackageName:Package_for_RollupFix~31bf3856ad364e35~amd64~~26100.7840.1.0
      

      (Package name here is an example; use the one shown on the system.)
   4. Restart the device.
   5. Reinstall KB5077181 using Method A or B above.
   Note: The combined package includes the Servicing Stack Update (SSU). The SSU portion cannot be removed; only the LCU can be removed with DISM. Using wusa.exe /uninstall on the combined package will not work.
4. If issues persist After these steps, if KB5077181 still fails with 0x800f0983, repeat the dism /online /cleanup-image /startcomponentcleanup command, restart, and then rely on the manual Catalog installation (Method A). If the error continues, advanced troubleshooting (logs analysis, in‑place repair install) would be required beyond what is covered in the provided context.
