Several users and industry pundits that The Star spoke to believe Microsoft is using its WGA campaign to herd business users into upgrading to its newest operating system, Windows Vista, which hasn’t garnered interest among companies because of its higher hardware requirements.

“Microsoft has stopped selling Win XP in the market, so you have to wonder why it is spending time and money to take down users of pirated copies of this OS,” said a PC user, who asked for anonymity. “Why isn’t it also targeting users who have pirated copies of Windows Vista?”

“So if I’m using a pirated copy of Vista at this time, I won’t be hassled? Got to wonder about that.”

Ng replied that the concern now is XP Pro, which is widely pirated. “Vista isn’t pirated as much. WGA is continuous and should there be a Vista piracy problem, we will address it down the road,” he said.
