Windows 10: product key where is it for windows 7 pro

cant find my product key for my update to 10 only found a partial key

:)

 

Will a Windows 7 Ultimate key activate Windows 7 Pro?

No - Typically as far as I know, a Windows 7 Ultimate key will unlock Windows 7 Ultimate.

The thing is basically what is on the INSTALLATION disc is usually exactly the same no matter what version you buy, ALL the potential content is already on the disc, and it is the Product Key itself that tells the installer what options to install/how to install them, so that you land up with your specific product.

Take an Ultimate DVD, install , but enter a windows Home key, and you will most likely get a Home install.

... or am I 'trippin? Pro's weigh in?

 

Will a Windows 7 Ultimate key activate Windows 7 Pro?

I've tried the opposite, was installing Win7 on a friends comp, my copy of win 7 (home premium) and his key (pro). When I entered the key, it gave me an error regarding versions. Skipping the initial key input also lead to a version error thing when Windows booted up. One big thing I noticed when I did that was it didn't let you choose the version to install if you skipped the key input. In short Vista lets you use whatever disc to install, 7 doesn't.
