Step-by-Step Guide to Troubleshoot and Fix ERROR_435

Step 1: Restart Your Computer

Before diving into complex fixes, always restart your PC. Sometimes, a simple reboot clears temporary glitches causing the error.

Step 2: Run Windows Update

Microsoft often releases patches that fix known issues.

  1. Open Settings (Press Win + I).

  2. Go to Update & Security.

  3. Click Check for updates and install any available updates.

  4. Restart your computer after installing updates.

Step 3: Run the System File Checker (SFC) Tool

Corrupted or missing system files often cause ERROR_435. The SFC tool scans and repairs them.

  1. Press Win + S and type cmd.

  3. Type the following command and press Enter:

    sfc /scannow

  4. Wait for the scan to complete (this might take a while).

  5. If it finds errors and repairs them, restart your PC.

Step 4: Use the Deployment Image Servicing and Management (DISM) Tool

If the SFC tool didn’t fix the problem, DISM can repair the Windows image.

  1. Open Command Prompt as administrator (same as Step 3).

  2. Enter these commands one by one, pressing Enter after each:

    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth

  3. After completion, restart your computer.

Step 5: Check for Problematic Drivers

Outdated or incompatible drivers can trigger ERROR_435.

  1. Press Win + X and select Device Manager.

  2. Look for devices with a yellow exclamation mark.

  3. Right-click the questionable device and select Update driver.

  4. Choose Search automatically for updated driver software.

  5. If updates are found, install them and reboot.

Step 6: Remove Recently Installed Software

Sometimes new software conflicts with system processes.

  1. Press Win + I to open Settings.

  2. Navigate to Apps > Apps & features.

  3. Sort apps by Install date.

  4. Uninstall recently added programs one by one.

  5. Restart after each uninstall to check if ERROR_435 disappears.

Step 7: Perform a Clean Boot

A clean boot helps you identify if background services or startups cause the error.

  1. Press Win + R, type msconfig, and press Enter.

  2. Go to the Services tab.

  3. Check Hide all Microsoft services.

  4. Click Disable all.

  5. Go to the Startup tab and click Open Task Manager.

  6. Disable all startup items.

  7. Close Task Manager and click OK in the System Configuration window.

  8. Restart your computer to see if the issue persists.

  9. If fixed, re-enable services/startup items one by one to isolate the culprit.

Step 8: Restore Windows to a Previous Point

If the error started recently, restoring your system to a previous healthy state can help.

  1. Press Win + S, type Create a restore point, and open it.

  2. Click System Restore and follow the prompts.

  3. Choose a restore point before the error appeared.

  4. Complete the restoration and restart.

Step 9: Reset or Reinstall Windows (Last Resort)
