Ako je XP, onda se opcija zove "Add/Remove Windows Components" ili tako nešto. Ako je Vista, onda, kada otvoriš "Programs and Feature", sa leve strane imaš opciju "Turn Windows Features on or off". Samo vodi računa šta uklanjaš/dodaješ, jer možeš da narušiš neke stvari (naročito u Visti).
Ako je neki Windows Server u pitanju, onda se IIS uklanja iz liste instaliranih Rola (Server Roles).
"There is a theory which states that if ever anybody discovers exactly what the
Universe is for and why it is here, it will instantly disappear and be replaced by
something even more bizarre and inexplicable. There is another theory which states
that this has already happened."
