Question

I have windows 11 installed.

My Windows Update fails to install the 2024-03 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5035853). It gives the following error: Install error - 0x800706b

What I've tried:

• I've rebooted the PC several times.
• run sfc /scannow (shows no error)
• run DISM /Online /Cleanup-Image /ScanHealth (no errors)
• run DISM /Online /Cleanup-Image /RestoreHealth
• run sfc /scannow (again, after DSIM, shows no error)
• delete the following files:
  • c:\ProgramData\Application Data\Microsoft\Network\Downloader*.*
  • C:\Windows\SoftwareDistribution
  • C:\Windows\System32\catroot2
• reset security descriptor in Windows update and Bits sc.exe sdset bits
  • sc.exe sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

• Reset networking and flushdns
• Downloading the update from here (https://www.catalog.update.microsoft.com/Search.aspx?q=KB5035853) and try to install manually

Answer 1

I have the same issue - tried everything, even deleting the update folder.

Same error, over and over again.

Answer 2

Hello,

According to your description, you have tried a lot of methods just like reset Windows Update component, repair system file. If we try to install the update manually still failed, it is not related to network, I consider that some directory files, manifest files, or MUM files on your computer are corrupted. Dism command doesn't repair these files successfully. So you may try to perform a in-place upgrade with Win11 ISO to check.

If not, try to check the Windows Update log and CBS log (%Systemroot%\Windows\logs\CBS.log) to analyze the problem.
