A. To apply a .reg file (a registry information file) the normal
method from the command prompt is to enter
C:\> regedit <registry file>.reg
This applies the change and gives a confirmation message:
"Information is <filename>.reg has been successfully
entered into the registry"
If you would like to avoid this confirmation message and apply the
change silently use the /s switch, e.g.
C:\> regedit /s <registry
file>.reg
