store the Windows Registry on disk.  Hivex is a library that can read
and write to these files.

&#39, hivexsh&#39, is a shell you can use to interactively navigate a hive
binary file.

&#39, hivexregedit&#39, (in perl-hivex) lets you export and merge to the
textual regedit format.

&#39, hivexml&#39, can be used to convert a hive file to a more useful XML
format.

In order to get access to the hive files themselves, you can copy them
from a Windows machine.  They are usually found in
%systemroot%\system32\config.  For virtual machines we recommend
using libguestfs or guestfish to copy out these files.  libguestfs
also provides a useful high-level tool called &#39, virt-win-reg&#39, (based on
hivex technology) which can be used to query specific registry keys in
an existing Windows VM.

For Python 3 bindings, see 'python3-hivex'.

For Ruby bindings, see 'ruby-hivex'.");
