What Causes Windows Update Error Code 0x80240034?
Several issues can trigger this error, including unstable or restricted internet connections, corrupted Windows Update files, insufficient free disk space, damaged system files, problems with Windows Update services, antivirus or firewall interference, or outdated device drivers. The exact cause varies from computer to computer, so work through the solutions below in order.
Here’s how to fix Error Code 0x80240034:
Check your internet connection
Confirm other websites or online services work normally, restart your router if needed, and try a different network if possible. If connection-related problems continue, see our guide to Windows Update Error Code 0x8024402C.
Free up disk space
Open Settings → System → Storage to check available space. Remove unnecessary temporary files, empty the Recycle Bin, uninstall unused applications, or move large files to another drive. Restart and try the update again.
Run the Windows Update Troubleshooter
On Windows 11: Settings → System → Troubleshoot → Other troubleshooters → Windows Update → Run. On Windows 10: Settings → Update & Security → Troubleshoot → Additional troubleshooters → Windows Update. Restart and check for updates again afterward.
Run System File Checker
Open Command Prompt as administrator and run sfc /scannow. Wait for the scan to reach 100%, then restart. If corrupted files were found and repaired, try the update again. For a related issue involving damaged files, see our guide to Windows Update Error Code 0x800F0900.
Run the DISM tool
If SFC doesn’t resolve it, run each command below one at a time in an elevated Command Prompt, letting each finish first:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
Restart your computer after the final command completes, then check for updates.
Restart Windows Update services
Press Win + R, type services.msc, and press Enter. Find “Windows Update,” right-click it, and select Restart. Also check that Background Intelligent Transfer Service (BITS) is running, and start it if stopped. Restart your computer and try the update again.
Reset Windows Update components
In an elevated Command Prompt, run:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Restart Windows and check for updates. If Windows reports missing update files, see our guide to Windows Update Error Code 80073712.
Temporarily check security software
If you recently installed or changed antivirus or firewall software, temporarily check whether it’s blocking the update — don’t leave your computer unprotected for long, and re-enable it after testing.
Update your device drivers
Open Device Manager and check for devices showing warning icons. Update those drivers through the manufacturer’s official support channel, then restart your computer.
Try Windows Update again
Go to Settings → Windows Update (Windows 11) or Settings → Update & Security → Windows Update (Windows 10), install any available updates, and restart if prompted.
