I recently bought Dell laptop that has 2010 office professional plus and since I bought is used I don't have product key and original owner don't have product key any more....

I want to format and re-install windows 7 and this office 2010 ..

I can bring it to factory original using dell recovery manager but don't have 2010 office installation media

so what is the reliable source to get office installation medial for free?

Also, how can I extract product key from office 2010 which is already installed on this laptop? I know I can use windows 7 key from bottom of laptop sticker but there is no key for office any where...

I am not sure key extracted my software like jelly bean will give reliable key?

So what is the reliable way to get extract office key?

Hi,

Microsoft doesn't provide a method to retrieve the complete product key after the installation. To get assistance on this issue, I suggest you contact the customer service, since in this forum we mainly discuss technical questions.

As long as you have the product key, you can download Office 2010 from this link below, press Download button under "Download or get a backup for Office 2010" and input the product key:
