    I'm trying to upgrade to Windows XP Professional Edition from XP Home Edition, but I can't get past the part of the installation where you are asked to enter the Product Key for your copy of Windows. Every time I enter the Product Key from the sticker on the underside of my laptop, it tells me that it is invalid. I've entered it millions of times, going left to right as well as right to left just to make sure it's not a mental slip, so I'm sure that I'm entering what's on the sticker. So my question is: where do I go from here? I've tried using several different programs that scan your registry for the Product Key, but those keys were invalid too. Should I contact the manufacturer to see if they made a mistake with the sticker? Any help would be appreciated. Thanks. - Pete

    The XP Pro requires a different key than the Home that came with your PC

    You are entering the XP Home registration number.You need to enter the serial number provided with the XP Pro CD which you purchased then register it with MS within 30 days of installation or it will become inoperable.

    Howdy pete c12, You can also contact Microsoft support site and tell them of your problem and they can contact you by email. They are quite helpful.
