What Is Windows Error Code ERROR_397?

ERROR_397 is generally a system error related to issues in system files, driver conflicts, or corrupted registry entries. It can appear during software installations, updates, or even during normal Windows operations, leading to failed processes and error pop-ups.

Common symptoms of ERROR_397 include:

  • Inability to install or update software
  • Unexpected system crashes or freezes
  • Program errors stating “Error Code 397”
  • Blue Screen of Death (BSOD) in some cases


Why Does ERROR_397 Occur?

Several factors can trigger this error, including:

  • Corrupt or missing system files
  • Conflicting or outdated device drivers
  • Malware or virus infection affecting system processes
  • Incorrect registry entries or settings
  • Windows update failure or incomplete installation

Knowing these causes highlights the importance of thorough troubleshooting, which we cover next.


How to Fix Windows Error Code ERROR_397: Step-by-Step

Step 1: Restart Your Computer

Sometimes, simple glitches cause temporary error codes:

  • Save your work.
  • Click Start > Power > Restart.
  • After reboot, check if the ERROR_397 still appears.

If it persists, move on to the next step.


Step 2: Run Windows System File Checker (SFC)

Corrupted system files often cause unexpected errors. The built-in SFC tool scans and repairs these files.

  1. Press Windows key + S, type cmd.
  2. Right-click Command Prompt, select Run as administrator.
  3. In the Command Prompt, type:

    sfc /scannow

  4. Press Enter.
  5. Let the scan complete (this could take several minutes).
  6. Review the results. If corrupted files were fixed, restart your computer and check for the error.


Step 3: Run the DISM Tool

If SFC doesn’t completely fix the error, the Deployment Image Servicing and Management (DISM) tool can repair the Windows image:

  1. Open Command Prompt as administrator again.
  2. Enter 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

  3. Wait for each process to complete.
  4. Restart your PC and verify if the problem is resolved.


Step 4: Update Device Drivers

Outdated or incompatible drivers can trigger ERROR_397.

  1. Press Windows key + X, click Device Manager.
  2. Expand critical categories such as Display adapters, Network adapters, Sound, video and game controllers.
  3. Right-click each device, select Update driver.
  4. Choose Search automatically for updated driver software.
  5. Follow prompts and repeat for all important devices.
  6. Reboot your system afterward.

Alternatively, visit your device manufacturer’s website to download the latest driver versions manually.


Step 5: Perform a Full Malware Scan

Malicious software can inject errors into system processes.

  • Open Windows Security by searching in the Start menu.
  • Go to Virus & threat protection.
  • Click Scan options > Full scan.
  • Allow Windows Defender (or your antivirus) to scan and remove threats.
  • Restart after scan completion.


Step 6: Clean Up and Repair Registry Entries

Invalid registry keys related to software installations or system settings can cause ERROR_397.

⚠️ Warning: Editing the registry manually can be risky. Consider backing up your registry before proceeding.

To safely clean registry errors:

  • Use trusted third-party software like CCleaner to scan and fix registry issues.
  • Avoid downloading unverified registry cleaners.

Run the cleaner, repair all detected errors, reboot your PC, and check if the error is gone.


Step 7: Check Windows Update Status

Incomplete or corrupted Windows updates can trigger errors:

  1. Open Settings > Update & Security > Windows Update.
  2. Click Check for updates.
  3. Install any pending updates.
  4. If updates fail, run the Windows Update Troubleshooter:

    • Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
    • Select Windows Update, then Run the troubleshooter.
  5. Follow the on-screen instructions and reboot.


Step 8: Use System Restore (If Applicable)

If ERROR_397 started recently, restoring your system to an earlier working state might help.

  1. Type Create a restore point in the Start menu and open it.
  2. Click System Restore.
  3. Choose a restore point dated before the error started.
  4. Confirm and let Windows restore your system.


Step 9: Reset or Reinstall Windows (Last Resort)

If none of the previous steps work, resetting or reinstalling Windows may be necessary:

  • Go to Settings > Update & Security > Recovery.
  • Click Get started under Reset this PC.
  • Choose whether to keep or remove your personal files.
  • Follow prompts to complete the reset.

Place backup your important files before proceeding!


Tips to Prevent ERROR_397 in the Future

  • Keep your Windows OS and drivers updated.
  • Regularly scan your system for malware.
  • Avoid installing unverified software.
  • Perform routine system maintenance such as disk cleanup.
  • Back up your system regularly.
