Very little is not compatible with 7. At work we havent had a single issue on any machine we’ve migrated. Machines we could migrate to vista due to software isses we now can migrate to 7 and work flawlessly. Personal experiance with it, I’ve loaded it on low end machines/high end machines… Shit with old ass hardware. Used weird ass programs that havent been updated since Windows XP was released etc… Not a single issue where as vista hated life
