Not true. At least two class action lawsuits have been filed over WGA "false positives". Some people estimate the error rate for WGA verification is as high as one in seven.
If you do receive a false positive somehow, you could just contact Microsoft about it, problem fixed.
The WGA false positive dialog does not even include Microsoft's support phone number. It just has a link to an online store where you can purchase another license. I'm sure a lot of innocent people get scammed into buying another license by this, hence the lawsuits. If you've lost the paperwork that came with your copy of Windows, you're up the creek. Phoning Microsoft doesn't help in that case.
