The article [Q183887] explains that when a computer is started successfully, the Windows Registry Checker tool (Scanreg.exe) creates a backup of system files and registry configuration information (including user account information, protocol bindings, software program settings, and user preferences) once daily. Files backed up include, System.dat, User.dat, System.ini, and Win.ini. To use this tool with the /restore parameter, the tool must be run from a command prompt (booted to) outside of Windows, where one of up to five registry backup files may be chosen from the list to restore.
Somehow I've messed up my start menu. When I press on the start button, all that shows up is MS Word and Open New Document. All of the rest of the selections are gone. I even have to do a Crtl-Alt-Del to get to a shutdown button to turn off the computer. How do I restore the start menu? I am running Win98 on a 733mhz computer with 128mb ram.
