I've experimented installing Windows 8 from an installation DVD on several bran name computers which makes a nice clean install without all the junk that comes with these computers. But it doesn't always work. Sometimes it will recognize the product key embedded on the motherboard and sometimes it won't then ask for one which you can't provide as it's hidden. And as far as I can tell, I can't use a Windows 8.1 installation DVD when the PC came pre-installed with Windows 8. What I would love to do is create an install disc with winreducer with all the updates (I hate Windows Updates beyond words) and be able to just make clean installs on new bran name PC's for customers willing to pay extra for a clean system. As far as I know this should be legal as it still uses the original product key provided with the system. Does anyone have any experience or comments on this subject?
