What is Windows System Error Code ERROR_285?

Before diving in, it helps to understand what ERROR_285 means. This error code generally denotes a problem with the service controller or service communication in Windows. It can appear in logs or system notifications when an application or script tries to start, stop, or interact with a Windows service but fails due to permissions or corrupted configuration settings.


Common Causes of ERROR_285

  • Insufficient permissions: Your user account may not have enough rights to control the service.
  • Corrupted system files or services: Essential files related to the service might be damaged.
  • Corrupt or misconfigured service registry entries.
  • Third-party application conflicts or malware interference.
  • Outdated Windows updates or system drivers.


How to Fix Windows System Error Code ERROR_285: Step-by-Step

Step 1: Restart Your Computer

Sometimes, a simple system restart can resolve temporary glitches that cause service errors.

  1. Save any ongoing work.
  2. Click on the Start Menu.
  3. Select Power, then Restart.
  4. After reboot, check if the error persists.

If ERROR_285 is still there, proceed to the next step.


Step 2: Run Command Prompt as Administrator

Many service-related actions require elevated privileges.

  1. Press Windows key + S, type cmd.
  2. Right-click Command Prompt and select Run as administrator.
  3. When the Command Prompt window opens, you will perform the next few commands here.


Step 3: Verify and Repair System Files with SFC and DISM

Corrupted system files often cause service errors including ERROR_285.

  1. In the elevated Command Prompt, type:

    sfc /scannow

  2. Press Enter. This process will scan and repair system files. It might take several minutes.
  3. Once complete, run the next command to fix any system image corruption:

    DISM /Online /Cleanup-Image /RestoreHealth

  4. Press Enter and wait for the process to finish.
  5. Restart your PC and check if the issue is resolved.


Step 4: Check Windows Services Status

Ensure the problematic service is set to run properly.

  1. Press Windows key + R, type services.msc, and hit Enter.
  2. In the Services window, find the service linked with the error (if known).
  3. Right-click the service and choose Properties.
  4. Confirm the Startup type is set correctly, usually Automatic or Manual.
  5. Click Start if the service is stopped.
  6. Click OK and close the window.


Step 5: Adjust Service Permissions

If permissions are the root cause, adjusting them can help.

  1. Open Registry Editor by pressing Windows key + R, type regedit, press Enter.
  2. Navigate to:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services[YourServiceName]

  3. Right-click on the service key and select Permissions.
  4. Check whether your user account or the SYSTEM account has full control.
  5. If not, edit the permissions to grant full control carefully.

Important: Editing the registry incorrectly can cause system issues. Consider backing up the registry first via File > Export.


Step 6: Update Windows and Drivers

Outdated system components can cause many errors.

  1. Go to Settings > Update & Security > Windows Update.

Malicious software can interfere with system services.

  1. Use Windows Defender or another trusted antivirus to perform a full system scan.
  2. Remove any threats detected.
  3. Reboot your PC and verify if ERROR_285 is gone.


Step 8: Perform a System Restore (Optional)

If the error started recently after changes or updates:

  1. Press Windows key + S, type Recovery, open Recovery Settings.
  2. Click Open System Restore.
  3. Choose a restore point before the error occurred.
  4. Follow prompts to complete restoration.
  5. Check if the issue is fixed afterward.


Step 9: Reinstall the Affected Application or Service
