It depends on the installation technology you use.

With MSI, you can pass /passive switch to msiexec command to prevent any interaction; add /norestart to prevent automatic system reboot. In case of MSI, you can also use Windows Installer API functions to fully programmatically install the package.

UI level can also be controlled from within the MSI package: from no UI at all to fully fledged wizard-like GUI. For example, you can display wizard interface when user installs your application for the first time; when you're preforming upgrade, you can show user only the progress or you can completely hide the UI.

Like @AlexeyI says, it depends on the installer you're using.

For InstallShield-created 'setup.exe' installers, you pass the /s(ilent) switch. If you need to provide answers to dialogs you also supply a response file containing the responses you want to give.
