Restoring the Windows 98 Registry
In order to restore one of the previous five registry backups:
Windows 98 stores 5 copies of the registry, SYSTEM.INI, and WIN.INI files by default. It creates a backup the first time you turn the machine on each day.
The Registry Checker scans the current registry for corruption or errors every time you start your computer.
If it finds a problem, it will allow you to load a previous version of the system registry.
Starting the Application
There are two uses for the Registry Checker. It can be used to make backups of the registry and it can be used to recover from a backup.
The first two methods given below give you access to the portion of the Registry Checker that allows you to make a registry backup. The last option below tells you how to recover a registry backup.
Backing Up the Registry
While Windows 98 only stores 5 backups of the registry by default, it is possible to change that number by editing the SCANREG.INI file and altering the MaxBackupCopies line. Each copy of the registry is stored in a file called RB0##.CAB, where ## is the number of the backup, such as 02 or 64.
These backups are stored in a hidden folder called C:\WINDOWS\SYSBCKUP.
Due to its design, the Registry Checker will only display the last 5 entries. This means that in order to get access to earlier backups, you will need to rename the registry entries you wish to access to RB000 through RB005.
You should be very careful when doing this, however, and should always make backups of the file you are about to replace.
