error code 0x800719E4 when trying to update windows

Error 0x800719E4 (ERROR_LOG_FULL) during Windows Update is commonly associated with full or corrupted transaction logs, ghosted network adapters or drivers, or update orchestration issues.

Try these steps in order:

1. Open Command Prompt as administrator and run:

      DISM /Online /Cleanup-Image /RestoreHealth
      SFC /SCANNOW
   

   If either tool repairs corruption, try Windows Update again.
2. If the error continues, clean the transaction logs. Warning: Incorrectly cleaning transaction logs can cause more issues. Open Command Prompt as administrator and go to:

      cd C:\Windows\System32\Config\TxR
   

   Then run:

      attrib -h -s *
      del *.blf
      del *.regtrans-ms
   

   Restart the PC and try the update again.
3. If the device has accumulated ghosted network adapters or drivers, that can also trigger this error. Detection and cleanup scripts are available in the Microsoft troubleshooting guidance. If ghosted devices are found, remove them and restart before retrying the update.
4. If the device uses a Mellanox adapter or driver, check for Mellanox devices in an elevated PowerShell window:

      Get-PnpDevice | Where-Object { $_.FriendlyName -like "*Mellanox*" }
   

   If a ghosted Mellanox device is identified, the documented removal command is:

      pnputil /remove-device <InstanceID>
   

   Restart and try the update again.

If Windows Update still fails after these steps, collect diagnostics with the TSS script and contact Microsoft Support.
