Symptoms

  • A feature update stalls at 0% or a low percentage, then fails with 0x80240034.
  • Windows Update history lists the feature update as “Failed to install.”
  • Cumulative updates install fine but the version upgrade will not.

What causes 0x80240034

  • The network is flagged as metered, capping the download.
  • A VPN or proxy interrupts the delivery.
  • The SoftwareDistribution\Download folder holds a partial package.

How to fix it

  1. Settings → Network & internet → your connection → turn off “Metered connection,” and disconnect any VPN.
  2. Clear the download cache and reset update components (command below).
  3. Run the Windows Update Assistant or create install media with the Media Creation Tool and upgrade in place, keeping files and apps.

Terminal / CLI command

net stop wuauserv && rd /s /q %systemroot%\SoftwareDistribution\Download && net start wuauserv

Elevated Command Prompt. The rd command clears only the Download subfolder.

How to confirm the fix: The feature update installs and Winver shows the new version after reboot.

Prevent it from coming back

Leave your main network unmetered and disconnect VPNs for version upgrades.
