If you’re seeing Windows ERROR_134, it can be a frustrating roadblock disrupting your workflow. Don’t worry—this guide will walk you through a comprehensive, easy-to-follow troubleshooting process to help you fix the issue quickly and get back on track.
What is Windows ERROR_134?
Windows ERROR_134 typically corresponds to an application failure error, often related to system or program crashes. It might appear as a popup message or a vague error code, leaving many users confused about what’s going wrong.
Common causes include:
- Corrupt system or application files
- Driver conflicts
- Software incompatibility
- Hardware issues (less common)
- Malware infections
Understanding the root cause helps guide your troubleshooting steps. Let’s get started!
Step 1: Note When Error 134 Occurs
Before diving into fixes, pay attention to:
- What program or action triggers ERROR_134?
- Does it happen during startup, shutdown, or while running a specific app?
- Are there any error messages or codes accompanying it?
Why this matters:
Identifying the context narrows down potential causes, saving you time later.
Step 2: Restart Your PC
This one might sound overly simple, but:
- Save your work.
- Restart your computer.
Why? Temporary glitches in Windows or applications often cause errors like ERROR_134, and a restart can reset the environment.
Step 3: Run Windows System File Checker (SFC) Scan
Corrupted system files are a common culprit.
How to run SFC:
- Press Windows Key + S, type
cmd. - Right-click Command Prompt and select Run as administrator.
-
In the command prompt, type:
sfc /scannow
- Press Enter.
- Wait patiently as Windows scans and repairs system files.
- When complete, restart your PC.
Step 4: Use Deployment Image Servicing and Management (DISM) Tool
If SFC didn’t fully fix issues, DISM is your next best option.
Steps to run DISM:
- Open Command Prompt as administrator (repeat step 3).
-
Type the following commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth - After DISM finishes, restart your PC.
Step 5: Check for Software Conflicts or Incompatibilities
- Update Windows: Go to Settings → Update & Security → Windows Update, then click Check for updates.
- Update the problematic app: If ERROR_134 appears when running a specific program, ensure it’s updated to the latest version.
- Disable startup programs temporarily:
- Press Ctrl + Shift + Esc to open Task Manager.
- Click the Startup tab.
- Right-click on any non-essential programs and choose Disable.
- Restart your PC and test.
If ERROR_134 stops, re-enable items one by one to identify the culprit.
Step 6: Update or Roll Back Device Drivers
Driver conflicts are another known cause.
To update drivers:
- Press Windows Key + X, select Device Manager.
- Find key hardware devices (display adapters, sound, network).
- Right-click device → Update driver → Search automatically.
- Follow prompts and restart.
If you recently updated a driver and started seeing ERROR_134 after, try rolling back:
- In Device Manager, right-click device → Properties.
- Go to the Driver tab.
- Click Roll Back Driver (if available).
Step 7: Perform a Clean Boot
A clean boot starts Windows with minimal drivers and startup programs, helping isolate third-party software causing issues.
How to clean boot:
- Press Windows Key + R, type
msconfig, and hit Enter. - Go to the Services tab.
- Check Hide all Microsoft services.
- Click Disable all.
- Go to the Startup tab → Click Open Task Manager.
- Disable all startup items.
- Close Task Manager, click OK in the System Configuration window.
- Restart your computer.
If ERROR_134 no longer appears, gradually re-enable services/startup items to identify the offender.
Step 8: Scan for Malware
Malicious software can trigger errors as part of their damage or spyware activities.
- Open Windows Security.
- Navigate to Virus & threat protection.
- Run a Full scan.
- Remove any threats found and restart.
Consider also using third-party trusted malware scanners for a thorough inspection.
Step 9: Check Your Hardware
Though less common, faulty hardware (RAM, HDD/SSD) can cause errors.
- Run Windows Memory Diagnostic tool: Press Windows Key, type
Windows Memory Diagnostic, and select Restart now and check for problems. - Use tools like CrystalDiskInfo to check drive health.
If hardware issues surface, consider professional repairs or replacements.
Step 10: Last Resort – Reset or Reinstall Windows
If nothing works, you might need to reset or reinstall Windows:
-
Reset PC:
Go to Settings → Update & Security → Recovery → Reset this PC.
Choose to keep your files or remove everything. - Reinstall Windows:
Download the Media Creation Tool from Microsoft’s website and follow instructions.
Make sure to back up your important data before proceeding.
