No, they are not legit. The only place that you can get a legit windows activation key is from the manufacturerrs of windows themselves. Let me ask you something. If you really wanted to buy an iphone and you hadtwo places you can buy it. The first is an iphone store and the second is an electronic store. Where would you go to nuy the i phone. All of these vedors that sell windows activation keys are all pirates. Microsoft has never given people activativation keys so that they can sell them on their behalf. All of these keys are acquired by illegal means. Buying the key from microsoft may be expensive but it is the best option for you. If you cannot affored to buy it at such an expensive price then you have probably heard of the KMS activator that activates both windows os and microsoft office for 18 month and then have to be activated again. You can go for that option instead. it is completely free and you have nothing to worry about. You can use it to activate as many computers as possible.
