What is Windows System Error Code ERROR_278?
Windows Error 278 usually occurs when you try to start a Windows service, but the operation fails due to system-level issues such as corrupted files, misconfigured settings, or permission restrictions. This error message often reads:
“Error 278: The specified service has been marked for deletion.”
or
“Cannot start the service because of a system error.”
This can stop critical services from running, impacting your system’s stability and functionality.
Why Does ERROR_278 Occur?
Common causes include:
- Pending service deletion or improper service removal.
- Conflicts or corrupted service registry entries.
- Permission and system account issues.
- Malware or virus interference.
- Corrupted system files or updates gone wrong.
Understanding these reasons can help you prevent similar errors in the future.
Step-by-Step Guide to Fix ERROR_278 on Windows
Step 1: Restart Your Computer
Many service-related errors disappear after a simple reboot since Windows clears pending deletions on restart.
- Action: Save your work, then restart your PC.
- Why: This resets service status and clears temporary glitches.
If the problem persists after restart, continue with the next steps.
Step 2: Check if the Problematic Service is Marked for Deletion
Sometimes, Windows marks a service for deletion but doesn’t remove it until restart, causing ERROR_278 when trying to start it.
-
Action:
- Press Win + R, type
services.msc, and hit Enter. - Look for the service you’re trying to start. If it’s missing or greyed out, the service might be marked for deletion but still present in the system.
- If you know the service name, open Command Prompt as Administrator and run:
cmd
sc queryex servicenameReplace
servicenamewith the actual service name. - Press Win + R, type
- Why: If this shows the service is deleted or pending deletion, proceed to Step 3.
Step 3: Remove the Service Stuck in Deletion State
You need to clean up lingering registry entries or force delete the service.
- Important: Be cautious editing the registry. Consider backing it up first!
To delete the service entry:
- Press Win + R, type
regedit, and press Enter. -
Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
- Replace
<ServiceName>with the exact name of the problematic service. - Right-click on the service key and select Delete.
- Close Registry Editor and restart your PC.
- Why: This removes corrupted or incomplete service entries causing ERROR_278.
Step 4: Run System File Checker (SFC) to Fix Corrupted Files
Sometimes, corrupted Windows system files cause service errors.
- Open Command Prompt as Administrator.
-
Type:
cmd
sfc /scannow - Press Enter. The scan will check and fix system file corruption.
- Restart your PC once the scan completes.
Step 5: Check and Fix Windows Update Issues
Since updates can impact services, run the Windows Update troubleshooter:
- Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
- Select Windows Update and run the troubleshooter.
- Follow prompts and apply any repairs suggested.
Step 6: Verify Service Permissions
Incorrect permissions can cause services to fail starting.
- In services.msc, right-click the service, select Properties.
- Go to the Log On tab and verify the correct account is selected (usually Local System Account).
- If unsure, reset to Local System Account and check if the service starts.
Step 7: Scan for Malware
Malware can corrupt system services and registry entries.
- Use your preferred antivirus or Windows Defender to run a full system scan.
- Remove any threats and restart your PC.
Step 8: Perform a Clean Boot
A Clean Boot helps eliminate software conflicts.
- Press Win + R, type
msconfig, and hit Enter. - Under the Services tab, check Hide all Microsoft services.
- Click Disable all.
- Go to the Startup tab and click Open Task Manager.
- Disable all startup items.
- Close Task Manager, click OK in System Configuration.
- Restart your PC and try starting the service again.
Step 9: Reinstall or Repair the Application
If ERROR_278 relates to a third-party service/application:
- Uninstall the software.
- Download the latest version from the official site.
- Reinstall and restart your PC.
Step 10: Contact Microsoft Support
If none of the above steps work, and the service is critical:
- Visit Microsoft Support.
- Provide detailed information including error messages.
- They may offer tailored solutions.
