We bought an HP 2730p on Ebay, refurbished with Windows 7 Professional. It is saying that this version is not genuine and cannot be verified, and certain features will be disabled in 31 days. Coming from Ebay, I would not be surprised if it's counterfeit, but I'm hoping it's an error. Is there any way to fix this without actually buying a new version of Windows 7? What will be disabled, and will it be things that will hinder the usage of the computer? There should be an option to reset to factory settings. Does anyone know if the 2730 would reset to Vista or XP?
