    Change windows 7 product key WITHOUT reinstall [Home prem. -> Pro]


    Hello

    I recently scrapped a old laptop, and kept the Windows 7 Pro produkt key. My desktop has a windows 7 home premium edt.

    I wish to change to pro, but without reinstalling, and without losing the home premium. Is it possible to switch the pro and home edt. without reinstalling, or losing my home prem. key?

    (It seems i posted in wrong section first. sorry)

    You cannot use an OEM Product Key on any computer but the one it came with. If the Pro Key you have came from the original computer's COA sticker, or from a KeyFinder, then it's OEM, and CANNOT be transferred to the mew machine.
