Assuming someone wants to release/liberate their Windows product key from a pc that they are going to sale, what is the right way to do it, so that the key can be used on the next system that is bought?
I did some product key changes a few years back, but I'm not sure if that's the right way to do it, or if there's something else that needs to or should be done.
If possible, mention if the same approach will work for Windows 8.
Thanks.
