Registry Operations

Opening an Excel file with macros without having to say OK. Shows writing to the registry.
Sample registry reading code. Shows how to grab user name, computer name, workgroup.

If you intend to use REGEDIT from a boot disk, you'll need to use the L and R options to specify where the registry files are located. You can read the REGEDIT DOS help only from DOS (Not from a DOS window) by typing "regedit /?". If you're too lazy to reboot into DOS mode to see the command-line help, I'll show you:

REGEDIT [/L:system] [/R:user] filename1
REGEDIT [/L:system] [/R:user] /C filename2
REGEDIT [/L:system] [/R:user] /E filename3 [regpath1]
REGEDIT [/L:system] [/R:user] /D regpath2

  /L:system       Specifies the location of the SYSTEM.DAT file.
  /R:user         Specifies the location of the USER.DAT file.
  filename1       Specifies the file(s) to import into the registry.
  /C filename2    Specifies the file to create the registry from.
  /E filename3    Specifies the file to export the registry to.
  /S              Silent (don't ask user to confirm action).
  regpath1        Specifies the starting registry key to export from.
                  (Defaults to exporting the entire registry).
  /D regpath2     Specifies the registry key to delete.
