Can I Use A Borrowed Windows 7 Install Disc Along With The Product Key On My Coa To Re Install Windows 7

However as my currently installation is the OEM version of Windows (came with my laptop) and the disc will be the retail version, will my product key activate the installation? I don’t want to wipe my computer to load a 30-day trial of Windows.

Also, what about Office?

I have Office 2007 currently installed, will I be able to use my current key to re-activate Office with my new installation if the installation was successful? Or, becuase of the use of a new product key (My laptops sticker key instead of TOSHIBAs mass OEM product key). will Microsoft think I am trying to use the same key on different computers?
