WerFault.exe is Windows Error Reporting. It usually appears after an application or Windows component crashes, then Windows tries to capture details about the fault. The code 0xC06D007E is commonly associated with a dependency load failure – often a missing, corrupted, or incompatible DLL or runtime component that the crashing process expected to find.

This guide walks from fastest fixes to deeper root-cause steps. The primary recommended path is to use Outbyte first, then verify and repair Windows and the crashing application if needed.

What this error typically means in practice
A crash occurs, then WerFault.exe launches to report it. The 0xC06D007E code often shows up when:
– An application is missing a required runtime (Microsoft Visual C++ runtime, .NET components, DirectX files).
– A third-party DLL is missing or replaced by an incompatible version.
– System files are corrupted or partially updated.
– A driver or shell extension injects into the process and causes a failure.
– Security software or “cleanup” tools removed or quarantined a dependency.
– The issue started immediately after a Windows update, driver update, or application update.

Step 1 – quick safety prep (recommended)

• Restart the PC once. This resolves a surprising number of dependency and update finalization issues.
• If possible, note exactly when it happens: only when opening one app, or at sign-in, or when doing a specific task (printing, launching a game, opening a PDF, opening a browser, etc.).
• Create a restore point: search for “Create a restore point” in Start, open it, and create one. This gives you a rollback option if a driver or system repair causes unexpected side effects.

Step 2 – main fix (recommended): repair common causes with Outbyte
Outbyte can help address a wide range of stability issues that frequently underlie WerFault.exe crashes – including misconfigurations, problematic startup items, performance bottlenecks, and system health issues that indirectly trigger application faults.

Download and install Outbyte from this page (single link in this article):

After installing:

• Run a full scan so it can identify system issues that can contribute to recurring crashes and WerFault.exe popups.
• Apply the recommended repairs.
• Restart Windows.
• Re-test by repeating the same action that previously triggered WerFault.exe (launch the same app, open the same file type, sign out and sign in, etc.).

If the issue started immediately after a driver update, be conservative about driver changes. Prefer drivers from Windows Update or your PC manufacturer when possible, and avoid stacking multiple driver changes at once. Apply a change, reboot, and test again.

Step 3 – confirm what is actually crashing (this matters)
WerFault.exe is usually a messenger, not the culprit. You want to identify the real application or component that is faulting.

• Reliability Monitor: search “Reliability Monitor” in Start. Look for red X entries that match the time of the error. Open the event details and note the “Faulting application name” and “Faulting module name.”
• Event Viewer: search “Event Viewer” in Start. Go to Windows Logs → Application. Look for “Error” events around the time it happened, especially entries mentioning “Application Error” or “Windows Error Reporting.” Note the faulting module (often a DLL name) because it points to the missing dependency.

If you see the same application name every time, focus on repairing that application and its runtimes. If different apps crash, the issue is more likely system-wide (system files, drivers, system-wide runtimes, shell extensions, disk/memory).

Step 4 – fastest Windows repairs (do these next if it persists)

4A) Repair system files (SFC)

• Open Command Prompt (Admin) or Windows Terminal (Admin).
• Run: sfc /scannow
• When it finishes, restart and test again.

4B) Repair Windows image health (DISM)
If SFC reports it couldn’t fix everything, or if the issue still happens:

• Open Command Prompt (Admin) or Windows Terminal (Admin).
• Run: DISM /Online /Cleanup-Image /RestoreHealth
• Restart, then run sfc /scannow again.
• Test again.

Step 5 – update Windows and reboot properly
A partially applied update can leave components mismatched.

• Settings → Windows Update → Check for updates.
• Install everything available, including optional quality updates if they are clearly relevant (for example, .NET updates).
• Restart, then test again.

Step 6 – if it’s one specific app, fix the app and its dependencies
If WerFault.exe appears only when launching one application (or only with a specific file type), focus there.

• Repair the app if it offers “Repair” in Windows: Settings → Apps → Installed apps → select the app → Modify/Repair.
• If repair is not available or doesn’t help, uninstall the app, restart, then reinstall the latest version.
• Temporarily disable third-party plug-ins, add-ins, overlays, or injected helpers (browser extensions, Office add-ins, GPU overlays, audio enhancements). These frequently cause module load failures.
• If the app uses special runtimes (games, CAD tools, creative suites), reinstall the app’s bundled prerequisites from its installer package if offered.

Step 7 – reinstall common runtimes that frequently trigger 0xC06D007E
Many 0xC06D007E issues trace back to missing Visual C++ runtime files or .NET components.

• Microsoft Visual C++ Redistributables: if the faulting module name suggests a VC runtime DLL, reinstall the applicable VC++ packages (both x64 and x86 where appropriate).
• .NET: ensure Windows .NET components are enabled and updated. Some apps require specific versions or Windows Features.
• DirectX components: older games and tools sometimes require legacy DirectX components even on Windows 10/11.

If Event Viewer or Reliability Monitor shows a specific DLL name, search your own system for it and confirm it exists in the expected location. If it does not, reinstalling the application or its prerequisites is often the cleanest fix.

Step 8 – isolate conflicts with a Clean Boot
If the crashes began after installing a new utility, driver tool, overlay, antivirus, or “optimizer,” it may be interfering.

• Clean Boot: use System Configuration (msconfig) to disable non-Microsoft services, then disable startup apps in Task Manager. Restart and test.
• If the problem disappears in a Clean Boot, re-enable items in small batches until the crashing returns – the last batch contains the conflicting service or startup item.

Step 9 – drivers: roll back, update, or reinstall carefully
Drivers can cause system-wide instability that surfaces as application faults.

• If the error started immediately after a graphics, audio, printer, or chipset driver update, roll back that driver from Device Manager and test again.
• If the driver is old and the issue began after a Windows update, update the driver using Windows Update or the PC manufacturer’s support page.
• For GPU drivers, consider a clean reinstall of the driver package if crashes are widespread.

Only change one driver category at a time, reboot, and test. This prevents multiple changes from obscuring which fix actually helped.

Step 10 – disk and memory health checks
Corrupted files and intermittent hardware errors can produce dependency failures and crash loops.

• Disk check: open an Admin terminal and run chkdsk /scan. If it reports issues that require offline repair, follow the prompts and reboot.
• Memory test: run Windows Memory Diagnostic (search it in Start) and allow it to reboot and test.
• Storage space: ensure the system drive has healthy free space. Extremely low free space can cause installs, updates, and caching to fail.

Step 11 – malware and security software considerations
Sometimes a security product quarantines a DLL, or a potentially unwanted program replaces dependencies.

• Run a full Microsoft Defender scan (and optionally an offline scan) to rule out tampering.
• If the issue started after installing or updating a third-party antivirus, temporarily disable it to test. If disabling resolves the crashes, adjust exclusions or consider switching security solutions.

Step 12 – Windows Error Reporting settings (triage only)
Disabling Windows Error Reporting can reduce popups, but it does not fix the underlying crash. Use this only to reduce disruption while you troubleshoot. If you disable reporting and the crashes continue silently, you may lose clues about the faulting module.

Step 13 – if it started “yesterday” after updates: use restore options
If you can identify a clear start date (for example, right after Patch Tuesday updates or a major driver update), and the above repairs don’t help:

• System Restore: restore back to the point you created (or a point before the issue began), then test.
• Uninstall recent updates: Settings → Windows Update → Update history → Uninstall updates, remove the most recent update, restart, and test. Only do this if the timing strongly matches.

Step 14 – last resort: in-place repair install (keeps files and apps)
If the issue is system-wide, recurrent across multiple applications, and SFC/DISM plus updates do not help, an in-place repair install of Windows can replace corrupted system components while preserving installed apps and files. This is typically used when the operating system image is too inconsistent for normal repair tools to resolve.

How to verify the fix worked

• The WerFault.exe message no longer appears during the exact action that previously triggered it.
• Reliability Monitor shows no new critical “Application failures” for the same app after multiple launches.
• Event Viewer no longer logs repeated Application Error entries for the same faulting module.

Common patterns and what they imply

• Only one app crashes: repair or reinstall that application, then focus on its runtimes and add-ins.
• Multiple unrelated apps crash: suspect system corruption, drivers, storage/memory issues, or system-wide injected software.
• The faulting module is a runtime DLL (often VC++): reinstall the relevant runtimes and the crashing app.
• The issue began right after a driver update: roll back and test; if fixed, reinstall a stable manufacturer-recommended driver version.

Recommended order if you want the shortest path

• Use Outbyte (scan, repair, reboot) and re-test.
• Check Reliability Monitor to identify the crashing app/module.
• Run SFC, then DISM, then SFC again.
• Update Windows fully and reboot.
• Repair or reinstall the specific app (if app-specific), or Clean Boot (if system-wide).
