Microsoft Nags U.S. Users of Fake Windows
If Microsoft thinks your copy of Windows is pirated, the software will display a nag screen upon login.What do they think their "stick" and "carrot" mean to knowledgeable users, anyway? Those wanting to control their own computer don't sign up for Automatic Updates, anyway. And with all the holes arising daily, anyone still using Insolent Exploder for a browser is in serious denial.
I love their locution "You may be a victim of software piracy" ... those using such programs are hardly "victims," though it's indeed true for MS's balance sheet. Other reasons exist to eschew such copies, but not the sense that one is "victimized."
Oh, their concern is justified, and so is offering this "helpful" "tool." (Standard property-rights disclaimers inserted here.) That doesn't make this effort on MS's part any less repulsive.
