Microsoft scaled back the scope and feature set of the new development project, sources have claimed, and focused on adding support for new consumer technologies that had become popular since Windows 98 was released. These primarily included digital music formats such as MP3 and digital video editing on the desktop. But some testers say the beta versions they've seen are riddled with more bugs than usual and that Microsoft is more hurried in its responses to bug reports, according to Bob Stein, of ActiveWin, a beta testing Web site. Microsoft disputes this depiction of the Windows Me development process. "The beta process is designed to encourage feedback. Bug reports are not only encouraged, but necessary," a spokesperson said. "I'm not aware of any of those claims, or of any information that would characterize the process as anything other than routine." Others in the Microsoft testing community believe Windows Me is on track. Paul Thurrott, editor of the WinInfo newsletter, has high hopes for the new OS.
