As far as wiping it, boot up like any winows disc go all the way to wherever it asks "where do you want to install windows" and format and delete the media drive, reformat it to whatever windows requires if you want to install it. Also probably useful that you keep the same version of windows for the keys b/c their in the bios.
Or when you plug it into another computer you can pull up disk manager and format or delete the drive and reformat it from there.
If you have mac or linux i dont know...
