4. Wait for both scans to finish. If they repair files, reboot.

How to troubleshoot (concise steps)

1. Restart the PC and check Windows Update again.
2. Run Windows Update Troubleshooter (Settings > Update & Security > Troubleshoot).
3. Restart Windows Update services:
   • Stop and start: Windows Update (wuauserv), Background Intelligent Transfer Service (BITS), Cryptographic Services.
4. Run SFC and DISM:
   • sfc /scannow
   • DISM /Online /Cleanup-Image /RestoreHealth
5. Clear update cache:
   • Stop wuauserv and BITS, delete contents of C:\Windows\SoftwareDistribution, then restart services.
6. Scan for malware with a reputable antivirus/antimalware tool.
7. Check Event Viewer for specific error codes/messages (Windows Logs > Application/System) and search those codes.
8. Repair or reinstall recent problematic updates via Settings > Update & Security > View update history > Uninstall updates.
9. Create a new user account to see if the issue is profile-specific.
10. If persistent, consider an in-place repair install of Windows or seek professional support.

Troubleshooting Steps

To resolve Wuauclt.exe crashes, follow these step-by-step troubleshooting solutions:

2.2 Third-Party Security Software

Antivirus or firewall software may:

• Hook into wuauclt.exe (DLL injection) and disrupt memory management
• Block the process from writing to temporary directories
• Misidentify legitimate network activity as suspicious → forced termination

3. Malware Infection or File Replacement

If wuauclt.exe is infected or replaced by a rogue executable, the genuine process cannot run correctly. The malware version might attempt to connect to external command-and-control servers, fail due to network restrictions, and crash—or be deliberately terminated by your antivirus, which then shows a wuauclt.exe crash error.

Red flags: High CPU usage by wuauclt.exe, unusual outbound connections, or the executable located outside C:\Windows\System32.

How to diagnose:

• Check file location: Right-click process in Task Manager → Open file location. Path should be C:\Windows\System32\wuauclt.exe. If it’s elsewhere, run a virus scan.
• Look in Event Viewer: Go to Windows Logs → Application. Look for Error events with source “Application Error” and faulting module name.

Fix 6: Scan for Malware (Even if You Trust Your PC)

Because impersonation is common:

1. Download Windows Defender Offline (built into Windows Security).
2. Go to Settings > Privacy & Security > Windows Security > Virus & threat protection.
3. Click Scan options and select Microsoft Defender Offline scan.
4. Your PC will restart and scan before Windows loads. This catches rootkits hiding as wuauclt.exe.

Fix 7: Perform a Windows In-Place Upgrade

If none of the above resolves the issue (especially on Windows 10/11), download the Windows Media Creation Tool and select “Upgrade this PC now.” This reinstalls Windows while keeping your apps and files, fixing any deep-seated corruption in the update system. Open Command Prompt as Administrator
