As far as the legitimacy of the key I don't know. It is not illegal to sell them. It is very possible that the keys are Tech Net and MSDN keys that will get blocked soon.
Too cheap to be legit. But buy one, and google the key after you have got it. Paypal should be interested in that, if you want your money back.
checked his key with the ms diagnostic tool and it says its a 5 retail key.... google shows no records of it at all Diagnostic Report (1.9.0011.0): ----------------------------------------- WGA Data--> Validation Status: Genuine Validation Code: 0 Cached Validation Code: N/A, hr = 0xc004f012 Windows Product Key: *****-*****-*****-*****-***** Windows Product Key Hash: Z0RB7JVfdOia++o+rbInxR9CU1k= Windows Product ID: 00426-066-2302815-86990 Windows Product ID Type: 5 Windows License Type: Retail Windows OS version: 6.1.7600.2.00010100.0.0.001 ID: {81D96A0B-1C47-4BCE-807E-328716FFB79E}(1) Is Admin: Yes TestCab: 0x0 WGA Version: N/A, hr = 0x80070002 Signed By: N/A, hr = 0x80070002 Product Name: Windows 7 Ultimate Architecture: 0x00000009 Build lab: 7600.win7_rtm.090713-1255 TTS Error: Validation Diagnostic: Resolution Status: N/A
I have signed up with eBay and PayPal to buy a product key for 7 Ultimate and am waiting for my 4 digit code to arrive.I will let you know if it works ok.I mean you should be able to get a full refund from PayPal if not genuine or the key expires.I have a theory that these keys are from system builders who buy the keys in volume and are selling them off to us for a little profit.
I see you mean not tied to bios, but still oem. Will your win7 details show it as oem, after you use code. I am sure ms are too looking into why people are selling these on ebay. But at the price not a bad risk.
