Nader and Love asked the Justice Department to focus on the barriers to entry of alternative operating systems. The Justice Department, which has filed a wide-ranging lawsuit against Microsoft for its business practices, had no immediate comment on the letter. Nader and Love said a 1995 consent decree between the Justice Department and Microsoft was supposed to clear the way for PC makers to sell Intel-compatible computers without Microsoft operating systems, but that it appeared to be ineffective. They suggested that one possibility to open up the market would be to load some computers with two operating systems and asked, "Do [computer-makers] have the unambiguous right to sell PCs with Windows and a non-Microsoft OS on the same machine, sharing the same hard drive?"
