With all the Windows 10 craze going on at the moment I felt like I should take my unregistered spare Windows 8 machine and activate it so I can pull Windows 10 down.. My dell machine that I am on right now typing this is running linux, however has a windows 8 pro key in the bios… Since I’m not using the key nor do I plan to on this machine, I wanted to pull this out and use it for the activation on the other machine.. So here it is fairly simple #NOTE I believe this could be done via a linux live cd if you are on Windows currently:
Look for something that says “MSDM”
cat the file out and it will display your product key that came with the machine.. It may come out looking a little funky but I was able to read it well enough… I have verified that the key works on my second windows 8 machine.. #NOTE: I have randomly changed letters and numbers in the product key below so that it will not be used or redistributed.
