If you don't want to deal with the instability of 2004-era code, you can use modern projects that simulate the experience:

Development of Longhorn began in 2001 after Windows XP’s release, targeting a 2003 launch. However, due to feature creep, security rewrites, and management upheaval (the “reset” in August 2004), Longhorn became one of the most infamous vaporware-to-shipping transitions in tech history. Before the reset, early builds (e.g., 3683, 4008, 4015, 4074) featured revolutionary UI concepts: the , a sidebar with tiles (WinFS-powered widgets), a dynamic “Avalon” (WPF) presentation layer, and a new file system (WinFS).
