Hi @Yan, Jayden,

To silently clean uninstall SQL Server 2014, you can use the following steps:

1. Open a Command Prompt with administrative privileges.
2. Navigate to the directory where the SQL Server 2014 setup executable is located.
3. Run the following command to launch the setup program in silent mode: Setup.exe /q /ACTION=uninstall /FEATURES=SQL /INSTANCENAME=YourInstanceName /IACCEPTSQLSERVERLICENSETERMS Optionally, you can use the /QUIETSIMPLE parameter to suppress any dialog boxes that may appear during the uninstallation process.

This is a general command. However, if you have installed additional SQL Server components such as SQL Server Reporting Services or SQL Server Analysis Services, you will need to specify those components in the command line by modifying the "/FEATURES" parameter accordingly.

For example, if you have installed both the Database Engine and Reporting Services, you would modify the "/FEATURES" parameter to "/FEATURES=SQL,RS" to uninstall both components.
