Comprehensive List of ERUNT Commands with Descriptions

**ERUNT** (Emergency Recovery Utility NT) is a utility for backing up and restoring the Windows Registry. It is particularly useful for creating registry backups that can be restored in case of system failures. Below is a detailed list of ERUNT commands, along with descriptions and examples.

---

1. Backing Up the Registry
Description: Creates a backup of the entire Windows Registry. By default, the backup is stored in a folder named after the current date.

Code:

erunt.exe [BackupPath]

Example: To back up the registry to `C:\RegBackups`:

Code:

erunt.exe C:\RegBackups

Note: If no path is specified, ERUNT will create a backup in the `C:\WINDOWS\ERDNT` directory by default.

2. Backing Up the Registry with a Custom Folder Name
Description: Creates a registry backup with a custom folder name instead of the default date-based name.

Code:

erunt.exe [BackupPath]\[CustomFolderName]

Example: To back up the registry to `C:\RegBackups\MyBackup`:

Code:

erunt.exe C:\RegBackups\MyBackup

3. Silent Mode Backup
Description: Performs a registry backup without displaying any prompts or confirmation dialogs.

Code:

erunt.exe [BackupPath] /noconfirmdelete /noprogresswindow /days:0

Example: To silently back up the registry to `C:\RegBackups`:

Code:

erunt.exe C:\RegBackups /noconfirmdelete /noprogresswindow /days:0

4. Automated Daily Backup
Description: Configures ERUNT to create daily backups automatically, storing backups in a specified directory.

Code:

erunt.exe [BackupPath] /days:[NumberOfDays]

Example: To set up automated daily backups in `C:\RegBackups` and keep backups for 7 days:

Code:

erunt.exe C:\RegBackups /days:7

5. Restoring the Registry from a Backup
Description: Restores the registry from a previously created backup. The restoration process should be performed from Safe Mode or from outside of Windows.

Code:

erdnt.exe [BackupPath]

Example: To restore the registry from a backup located in `C:\RegBackups\20230902`:

Code:

erdnt.exe C:\RegBackups\20230902

6. Restoring the Registry Silently
Description: Restores the registry without any prompts or user interaction.

Code:

erdnt.exe [BackupPath] /silent

Example: To restore the registry from a backup located in `C:\RegBackups\20230902` without any prompts:

Code:

erdnt.exe C:\RegBackups\20230902 /silent

7. Backing Up Only Specific Parts of the Registry
Description: Allows you to back up only specific registry hives such as `SYSTEM`, `SOFTWARE`, or `DEFAULT`.

Code:

erunt.exe [BackupPath] /registry [hive1] [hive2] ...

Example: To back up only the `SYSTEM` and `SOFTWARE` hives to `C:\RegBackups\PartialBackup`:

Code:

erunt.exe C:\RegBackups\PartialBackup /registry system software

8. Creating a Backup and Including the User Registry
Description: Backs up the entire registry including the user registry hives (`NTUSER.DAT`).

Code:

erunt.exe [BackupPath] /user

Example: To back up the registry including the user registry to `C:\RegBackups`:

Code:

erunt.exe C:\RegBackups /user

9. Restoring the Registry with the User Registry
Description: Restores the entire registry including the user registry hives.

Code:

erdnt.exe [BackupPath] /user

Example: To restore the registry including the user registry from `C:\RegBackups\20230902`:

Code:

erdnt.exe C:\RegBackups\20230902 /user

10. Automating the Backup Process via Task Scheduler
Description: Automates the backup process by scheduling it with Windows Task Scheduler. This is not a direct ERUNT command but can be set up using Task Scheduler.

Code:

schtasks /create /tn "DailyRegistryBackup" /tr "C:\Path\To\erunt.exe C:\RegBackups /noconfirmdelete /noprogresswindow /days:7" /sc daily /st 02:00

Example: To create a daily registry backup at 2 AM:

Code:

schtasks /create /tn "DailyRegistryBackup" /tr "C:\ERUNT\erunt.exe C:\RegBackups /noconfirmdelete /noprogresswindow /days:7" /sc daily /st 02:00
