This command-line utility searches for and allows you to delete Registry keys that contain embedded-null characters and that are otherwise undeleteable using standard Registry-editing tools. Note: deleting Registry keys may cause the applications they are associated with to fail.
Usage: regdelnull <path> [-s]
| Parameter | Description |
