|There's no START--SETTINGS--CONTROL PANEL? Sometimes the registry is edited to disable certain things. It's usually hard to fix as the registry editing command, regedit, is often disabled too.|
No recovery disks?
9X doesn't have restore points like later OS's so there's no way to revert back to a particular time.
Best thing would be to locate a 98 cd and do a fresh installation. You can always download a bootdisk file for a floppy disk from someplace like bootdisk.com but it's pretty much useless without a cd to do the actual installation.
