To restore the backup manually On the Start menu, click Shut Down. Select Restart in MS-DOS mode and click OK. At the MS-DOS command prompt, type scanreg /restore. Select the latest known good backup. Backed up, compressed registry files are listed with the name Rbxxx.cab. The files show the time and date of backup. Next to each CAB file are the words Started or Not Started. Started means that the file has successfully started Windows 98, and is a known good file. Not Started means that the file has never been used to start Windows 98, so it is not a known good file.Good luck.
