When you install Windows 2000, your initial registry hives are backed up to the %SystemRoot%\Repair folder.
When you create a new ERD, in NTBackup, and check the also backup the registry to the repair directory...... box,
the updated registry hives are stored in the %SystemRoot%\Repair\RegBack folder. A System State backup also updates the %SystemRoot%\Repair\RegBack folder.
You can use entries in the %SystemRoot%\Repair folders' hives to reset your current registry.
After an Administrator deleted the Recycle Bin registry entries, I used the following steps to recover them:
01. Using Regedt32, I selected the HKEY_LOCAL_MACHINE hive.
02. On the Registry menu, I pressed Load Hive.
03. I browsed to the %SystemRoot%\Repair folder and loaded the Software hive.
04. I entered JSI in the Key Name box.
05. With Regedt32 still open, I used regedit to export
06. I exited Regedit.
07. In Regedt32, I selected the JSI hive and pressed Unload Hive from the Registry menu.
08. I exited Regedt32.
09. I used notepad to edit the two .REG files, replacing \JSI\ with \Software\.
10. I double-clicked each .REG file and restarted the computer.
NOTE: You may wish to delete an keys that you are about to replace, to insure that no new values/sub-keys remain.
NOTE: See tip 2880 for the Windows NT 4.0 procedure alterations.
