You should find the key on a sticker attached to the retail product CD/DVD case or on a label affixed to your computer if it shipped with Windows installed. If you can't find the product key sticker, use free third-party software to retrieve the product key from the operating system itself.

I need to know where to find my product key number. I cannot use some programs without it. I did receive a product key number from Norton Security systems but when I try to use it, the system says it is incorrect. The number I have is <<Removed>>. Can you confirm this is correct or tell me where to access the correct product key number.
I hope to hear from you soon regarding this matter. Anything you can do to help will be greatly appreciated.
Sincerely,
Joan Fritz

You don't have *a* product key. You probably have a product key for each of several different products. For example, if you are running Windows 7, you certainly have a Windows 7 product key. If you have Microsoft Office installed, you have an Office product key. And if Norton uses a product key, then you have a Norton product key. Advanced systme care 9 serial key. And several other programs use product keys too. A single product key can not be used for several different products.

So when you say 'I need to know where to find my product key number. I cannot use some programs without it' that makes no sense. Each of the programs that you can't use has its own product key, so please tell us which programs you are asking about and where you got the programs. Each of the programs should have come with its own product key in the package it came in.

And one remaining point: if you are asking about a product key for programs that are part of Microsoft Office (Word, Excel, PowerPoint, Outlook, etc.) and Office came with your computer, almost certainly what you have is only a trial version of Office, and you have no product key for it. Your trial period has expired, and if you want to continue using it, you now need to buy the product and get a key for it.
