You mean create a USB key from Windows ?

I'm thinking of using this method to revert back to an older os due to my mac slowing down with Sierra. Will I be able to install just Yosemite or el capitan? Without installing previous os upgrades? This way I can have a fresh mac book.

Hello,

Yes you can but with this method, we must make a clean install.

So, please sure you save all your data to another hard drive.
