Windows Update Error Code 0x80096004 can appear when Windows can’t verify the digital signature of a file required during an update or installation. Corrupted system files, security software, and damaged Windows components can also contribute to the problem.
When Windows can’t validate a required file, the update may fail before installation completes. This guide explains the steps to fix it.
What Causes Windows Update Error Code 0x80096004?
The most common causes include corrupted or missing Windows system files, damaged update components, problems with digital signature verification, malware, third-party antivirus software, problems with update services, or network connectivity issues. Start with the simpler solutions first.
Here’s how to fix Error Code 0x80096004:
Run the Windows Update Troubleshooter
Windows 11: Settings → System → Troubleshoot → Other troubleshooters → Windows Update → Run.
Windows 10: Settings → Update & Security → Troubleshoot → Additional troubleshooters → Windows Update → Run the troubleshooter.
Restart your computer once it finishes, then check for updates again.
Run an SFC scan
Press Win + S, search for Command Prompt, right-click it and select “Run as administrator,” then run sfc /scannow. Wait for the scan to reach 100% and restart. If system-file corruption continues causing update problems, see our guide to Windows Update Error Code 0x800F0900.
Run DISM to repair Windows components
If SFC can’t repair all damaged files, run each command below one at a time in an elevated Command Prompt, letting each finish first:
DISM.exe /Online /Cleanup-image /CheckHealth
DISM.exe /Online /Cleanup-image /ScanHealth
DISM.exe /Online /Cleanup-image /RestoreHealth
Restart your computer once complete, then try the update again.
Temporarily check third-party security software
If you have third-party antivirus installed, temporarily disable its protection and check for updates again — don’t leave your computer unprotected for longer than necessary, and re-enable it after testing.
Check your internet connection
Open a few websites to confirm your connection works normally, restart your router if needed, and temporarily disconnect any VPN or check corporate proxy settings. If the problem seems connectivity-related, see our guide to Error Code 0x80240438.
Restart Windows Update services
Press Win + R, type services.msc, and press Enter. Find “Windows Update,” right-click it, and select Restart. Also check Background Intelligent Transfer Service (BITS) and restart it if it appears stuck. Restart your computer and check for updates.
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 your computer and try the installation again. If Windows continues to report missing or corrupted files, see our guide to Error Code 80073712.
Scan for malware
Open Windows Security → Virus & threat protection → Scan options → Full scan → Scan now. Remove any detected threats, restart your computer, and check Windows Update again.
Install Windows updates again
Go to Settings → Windows Update (Windows 11) or Settings → Update & Security → Windows Update (Windows 10), and select “Check for updates.” Avoid shutting down while installation is running.
