I was browsing ebay, found a bunch of very cheap Windows sever 2008 copies. The picture shows the complete retail box with contents inside, product tag, looks very authentic. They sell it with 30 day return and validation through phone or web have no problem(of course it should). The ebay seller has 100% positive feedback with 2000 sale history.
Now, the price is $99+shipping.
I think this is illegal copy even though it looks authentic. But I don't have any method to check if it is.
Is there any way to check if the copy of windows is a legal copy and whether it's already activated in use by looking at bar code? They posted a picture of bar code.
