# regdiff(1)

Diff program for Windows registry files

## NAME

regdiff - Diff program for Windows registry files

## SYNOPSIS

**regdiff** \[--help\] \[--backend=BACKEND\] \[--credentials=CREDENTIALS\] \[location\]

## DESCRIPTION

regdiff compares two Windows registry files key by key and value by value and generates a text file that contains the differences between the two files.

A file generated by regdiff can later be applied to a registry file by the regpatch utility.

regdiff and regpatch use the same file format as the regedit32.exe utility from Windows.

## OPTIONS

- \--help

  Show list of available options.

- \--backend BACKEND

  Name of backend to load. Possible values are: creg, regf, dir and rpc. The default is *dir*.

  This argument can be specified twice: once for the first registry file and once for the second.

- \--credentials=CREDENTIALS

  Credentials to use, if any. Password should be separated from user name by a percent sign.

  This argument can be specified twice: once for the first registry file and once for the second.
