There's not a day without some commercials about cro$fot...this is what i call hammering, washing people's brain.
You should be aware about unique user number assigned by the o.s. to your computer, spywares is nothing mysterious, "how to tell" is also a reality, you can use only approved hardware...poor captive consumer and poor industrials which must forcibly agree to be able to enter in the club and make money.
Also remember of the unique ID number associated with the cpu which first was a "feature" that could not be disabled...look at the innocent thing that you download when upgrading your windows...a bit of code which should identify if your install is genuine or not but who knows what this thing realy does ? The best is coming with the future vista and a lot of surprises in it.
