Uninstall SQL Server Completely

If SQL Server was not properly uninstalled, you can try the following methods to resolve the issue:

  1. Utilize the SQL Server Uninstall Tool: Microsoft offers a tool for uninstalling SQL Server that helps completely remove any leftover components. You can download and run this tool from the official Microsoft website.
  2. Manual uninstallation: If the uninstallation tool cannot resolve the issue, you can try manually uninstalling SQL Server. First, make sure to stop all services related to SQL Server. Then, use the Programs and Features option in the Control Panel to uninstall SQL Server. Additionally, you will need to manually delete SQL Server-related files and registry entries.
  3. Consider using a third-party uninstallation tool if the manual uninstallation process is complex or difficult, to help remove lingering files and registry entries of SQL Server.
  4. Reinstall SQL Server: If the above methods still don’t solve the issue, you can try reinstalling SQL Server before attempting the uninstall process again. Reinstalling may overwrite or repair damaged components, making the uninstall process smoother.
