[/v|-v]
This switch opens REGEDIT.EXE in advanced mode, where the registration database is displayed in a tree structure (similar to the tree window in Windows 3.1 File Manager). Any part of the database can be edited.
[/s|-s]
When a filename is specified on the command line, this switch is used to suppress any informational dialog boxes that would normally be displayed. This is useful when the Setup program for an application wants to execute REGEDIT.EXE with a .REG file, but does not want the user to be confused by any dialog boxes that are displayed.

/C filename2

/E filename3
Specifies the file to export the registry to.

Syntax for Switches Either "/" or "-" can be used to signify the optional switches. The switches can be combined (for example, -vs) and be typed in either uppercase or lowercase. Unrecognized switches are ignored.
