I bought a Sony Vaio laptop from HIDEvolution some time back (when windows 7 was in beta). At the time it was shipped with Windows Vista, but HIDEvolution contact person guaranteed that he will be sending a genuine copy windows 7 once he gets. Once windows 7 was released, he sent me the copy. But it was not a genuine one, and windows system is continuously complaining that the windows copy is not genuine. I tried to reach him atleast 15 times after this, and yet, there has been no response from him at all. Extremely disappointed with HIDEVolution after services.
