Techopedia explains Windows ME
Windows ME also introduced the Windows Image Acquisition API, which helps applications communicate with image acquisition equipment. It was the only operating system from the Windows 9x series to have generic drivers for Universal Serial Bus printers and storage devices. Windows ME introduced the System Restore functionality, which helps users return the state of their system to a prior stable configuration in case of installation problems. Windows Movie Maker was also introduced in Windows ME. Another important feature was Net Crawler, which automatically searches and creates shortcuts in My Network Places.
Windows ME restricted the real-mode DOS prompt, which was an important feature in earlier editions. Features like Microsoft Fax, Quick View, etc., were also removed from this edition. Some of the enterprise-oriented features present in earlier editions went unsupported in ME, such as Active Directory Client Services, System Policy Editor and Automated Installation. Some of the Windows Explorer commands also became obsolete in this edition. Despite the improvements, Windows ME was criticized for stability issues and bugs.
