In Windows systems, the setup /product server command can be used with the installation program to deploy or configure the server version of the operating system. The installation mode varies depending on the parameters provided with the command. Below is an explanation of common installation modes and their usage:

Installation Mode Explanation

1. Graphical User Interface Mode (GUI Mode)
   • The default mode, initiated by running the setup command.
   • Provides an intuitive interface where users can manually select options (e.g., disk partitioning, installation type, language settings, etc.).
   • Suitable for standard users or scenarios requiring customized installations.
2. Unattended Installation Mode
   • Uses a preconfigured answer file (e.g., autounattend.xml).
   • Command example: setup /unattend:autounattend.xml /product server
   • Usage scenarios:
     • Large-scale automated deployments.
     • Data center environments.
3. Command-Line Installation Mode
   • Completes the installation through the command line, ideal for environments without a graphical interface or for remote setups.
   • Supports parameters to specify product version and installation options.
   • Common parameters:
     • /product server: Specifies that the product being installed is Windows Server.
     • /quiet or /silent: Silent installation with no user interaction.
     • /noreboot: Prevents automatic reboot after installation.
4. Upgrade Mode
   • Used to upgrade an existing Windows system to the server version.
   • Example: setup /product server /upgrade
   • The system retains user data and settings during the process.
5. Repair Mode
   • Repairs an existing server operating system.
   • Example: setup /product server /repair
   • Useful for fixing boot issues or file corruption.

Common Options

• /quiet: Silent mode with no user intervention.
• /log:filename: Saves the installation log to a specified file.
• /rollback: Rolls back to the previous state if the installation fails.
• /installfrom:: Installs from a specified source.
• /recovery: Boots into recovery mode.

Recommendations

1. GUI Mode is ideal for single installations or testing.
2. Unattended Mode is suited for large-scale automated deployments, preferably using an answer file.
3. Command-Line Mode is best for headless environments or remote operations.
4. Repair Mode is useful for system recovery in case of failures.
