In this case, “naked” PCs are computers sold without a preinstalled operating system; ostensibly, a user would then install Linux or a BSD or some other operating system besides the latest Windows. A system with Windows preinstalled is more expensive, to cover the cost of the software.
Surprising no one, Microsoft is unhappy.
“We want to urge all system builders — indeed, all Partners — not to supply naked PCs. It is a risk to your customers and a risk to your business — with specifically 5 percent fewer opportunities to market software and services,” wrote [Michala Alexander, Microsoft’s head of anti-piracy].
Oh noes, Microsoft might lose its entrenched market dominance once it doesn’t have an iron grip on PC-makers! And they can’t preinstall the machines with six-billion crippled programs that make a computer run like shit out of the box! Whatever shall we do?
