Lesson Summary

The following points summarize the main elements of this lesson:

• MS-DOS 7, which comes with Windows 95, still uses the same three system files-IO.SYS, MSDOS.SYS, and COMMAND.COM-however, their functions are somewhat different.
• The principal visible difference between Windows 95 and Windows 3.x is the new GUI.
• The Registry is the principal operational difference between Windows 95 and earlier versions of Windows.
• The Registry is stored in three file locations: SYSTEM.DAT, USER.DAT, and the virtual registry.
• The Registry can be directly edited using REGEDIT.EXE, however, doing this is not recommended.
• Microsoft provides three ways to back up the Registry-Microsoft Configuration Backup (CFGBACK.EXE), the Emergency Recovery Utility (ERU.EXE), and REGEDIT.EXE. Each has its own advantages and limitations.
• The Device Manager is the key to managing the hardware on a Windows 95 system.
