Product keys for Microsoft Office 2003 mixed up

[NavinS]

There are 2 original copies of MS Office 2003 along with 2 different product keys. I have reinstalled one of those on a new Windows Vista computer after removing it from the old pc. The other one is for installation on a Windows XP computer. But the issue is by mistakenly I placed the 2 titles together and a wekk after installation of the first I forgot which was installed on the Vista pc Actually, the cases look exactly similar except for the Product Key on the back, I dont remember which one was installed. Can anyone tell me how to find the product key of the installed version? I am only able to find in the Registry and the Office itself is the Product ID and not the key. Any suggestions would be welcomed.

There are many softwares like Balarc Advisor or Magic Jelly Bean that will give you detailed information of your installed software and hardware, product key, network inventory, missing Microsoft hotfixes, anti-virus status, security benchmarks, and displays the results in your Web browser. Download it by searching it on the net.
