When you use the Registry Checker (Scanreg.exe) tool to restore a backupcopy of your registry, the backup from which you want to restore yourregistry may not be listed.
This behavior can occur if the Registry Checker tool is configured tomaintain more than five registry backups.
To work around this behavior, use either of the following methods:

NOTE: Because you can restore registry backups only from a command prompt,these methods assume that you are already at a command prompt.

Method 1

Configure the Registry Checker tool so that only the last five registrybackups are stored in the Windows\Sysbckup folder. To do so, follow these steps:
  1. At a command prompt, type the following lines, pressing ENTER after each line:

    cd \windows
    edit scanreg.ini
  2. Locate the "MaxBackupCopies=" line.
  3. Change the line to read as follows:

  4. Press ALT+F, press S (to save), press ALT+F, and then press X (to exit).

Method 2

If you are attempting to restore a later registry backup than the fivelisted in the Registry Checker tool, rename earlier registry backups untilthe backup from which you want to restore your registry is one of the fivelisted. To do so, type the following commands at a command prompt,pressing ENTER after each command

ren rb0<nn>.cab rb0<nn>.xxx

where <nn> is a number between 00 and 99.

NOTE: The lowest numbered registry backup may not be the earliest. Todetermine the earliest registry backup, check the date of the Rb<nnn>.cabfile.

For example, the Windows\Sysbckup folder contains seven registry backupsnumbered -, with being the earliest registrybackup and being the latest. To cause the Registry Checker toolto list the five latest backups, type the following commands:

The "MaxBackupCopies=" line in the Scanreg.ini file determines the numberof registry backups maintained in the Windows\Sysbckup folder. If the"MaxBackupCopies=" line is set to six or higher (five is the default), thecorrect number of registry backups is maintained in the Windows\Sysbckupfolder, but the Registry Checker tool can only display the five earliestbackups.
