Event ID 7023 in the Windows Event Viewer often persists after uninstalling Windows Subsystem for Linux (WSL) because background services or drivers fail to stop cleanly. This error indicates that a specific service terminated unexpectedly, leaving residual configuration states that trigger repeated warnings. The following guide outlines safe, standard diagnostic steps to identify the culprit and restore system stability without modifying critical registry keys.
Understanding Event ID 7023
The Event ID 7023 message is a generic "Service terminated unexpectedly" warning. It does not specify which service failed; it only reports that the Service Control Manager detected an abnormal exit. When WSL-related software is removed, remnants such as the Virtual Machine Platform, Hypervisor Platform, or legacy LxssManager components may remain registered in the system. If these services are set to start automatically but their associated binaries have been deleted or corrupted, Windows will attempt to launch them on boot, fail, and log this event repeatedly.
This issue is distinct from installation failures like Windows 10 Pro 64-bit Installation Error, which typically involve missing files during setup rather than post-uninstallation service crashes. Identifying the exact service name is the first critical step in resolving the noise in your Event Viewer logs.
Identifying the Failing Service
To resolve the error, you must determine which service is generating the 7023 event. The Event Viewer interface provides detailed properties for each entry that reveal the source component.
- Open the Start menu, type
Event Viewer, and launch the application. - Navigate to Windows Logs > System in the left-hand pane.
- Locate entries with Event ID: 7023. You may need to sort by date or filter the view by clicking "Filter Current Log" and entering
7023in the Event ID field. - Double-click the most recent entry to open its details window.
- Look for the General tab text. It usually contains a phrase like "The [Service Name] service terminated with the following error: Access is denied" or "The system cannot find the file specified."
The [Service Name] placeholder is the key identifier. Common candidates after WSL removal include LxssManager (if partially installed), WslSvc, or generic platform services like vmcompute. Note this exact name for the next steps.
Disabling or Removing Residual Services
Once the failing service name is identified, you can prevent Windows from attempting to start it. The safest method is to disable the service via the command line, avoiding manual registry edits which carry higher risks of system instability.
Open Command Prompt as Administrator by right-clicking the Start button and selecting Terminal (Admin) or Command Prompt (Admin).
If the service is still present but broken, you can change its startup type to disabled:
sc config [ServiceName] start= disabledReplace [ServiceName] with the actual name found in Event Viewer (e.g., LxssManager). After running this command, restart your computer. The error should no longer appear because Windows will skip starting the service during boot.
If the service binary is completely missing, you might need to remove the service registration entirely. Use the following command in the same administrative terminal:
sc delete [ServiceName]This command removes the service entry from the registry safely through the SC utility. Do not manually delete registry keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services unless explicitly instructed by Microsoft documentation, as incorrect deletions can break core OS functionality.
Verifying WSL Component Cleanup
After disabling the problematic service, ensure that other WSL components are correctly uninstalled. Sometimes, partial removal leaves behind hypervisor-level drivers that conflict with future updates. Check if the Virtual Machine Platform feature is still enabled in Windows Features.
Press Win + R, type optionalfeatures.exe, and press Enter. In the list, look for:
- Windows Subsystem for Linux
- Virtual Machine Platform
- Hyper-V (if applicable to your hardware and usage)
Uncheck any boxes related to WSL if you intend to use the system purely for native Windows applications. Apply changes and reboot. This step ensures that the underlying infrastructure for WSL is fully removed, preventing future conflicts.
If you encounter persistent errors despite these steps, consider checking for broader system issues. For instance, similar service termination errors can sometimes stem from driver conflicts or update corruption, as seen in Windows 10 Offline Upgrade Stuck at 21% with Error 0xC1900101-0x2000D. Running sfc /scannow in an admin terminal can repair corrupted system files that might be interfering with service management.
Frequently Asked Questions
Why does the error reappear after I disable the service?
If the error returns, it may be caused by a different service also failing to start, or a scheduled task triggering the service. Check the Event Viewer again to see if the Event ID 7023 now references a different service name. If it is the same service, ensure that the startup type remains disabled after a reboot.
Is it safe to delete the LxssManager service manually?
It is safer to use the sc delete command in an elevated command prompt rather than editing the registry directly. Manual registry deletion can leave orphaned keys that cause further confusion. Always verify the service name matches exactly what is reported in the Event Viewer before deleting.
Can this error affect my Windows performance?
No, Event ID 7023 is a logging warning and does not impact system speed or stability. However, a high volume of these events can clutter your logs, making it difficult to diagnose other real issues. Resolving the root cause cleans up the logs for better visibility.
What if I want to reinstall WLS later?
You can easily reinstall WSL by enabling the features in optionalfeatures.exe or using the wsl --install command in PowerShell. Disabling or deleting the residual service does not prevent future installation; Windows will create new service instances when you install the software again.
Does this error indicate malware?
Event ID 7023 itself is not an indicator of malware. It is a standard Windows service control manager response to a failed start. However, if you notice unusual network activity or unknown processes alongside these errors, run a full system scan with Windows Defender or a trusted antivirus tool to rule out malicious interference.
