python-registry is a pure Python library that provides read-only access to Windows Registry files. These include NTUSER.DAT, userdiff, and SAM. The interface is two-fold: a high-level interface suitable for most tasks, and a low level set of parsing objects and methods which may be used for advanced study of the Windows Registry. The library is portable across all major platforms.
Most users will find the
Registry.Registry module most appropriate.
The module exposes three classes: the
Registry organizes parsing and access
to the Windows Registry file. The
RegistryKey is a convenient
interface into the tree-like structure of the Windows Registry.
RegistryKey may have children
RegistryKeys, and may also have
values associated with it. A
RegistryValue can be thought of as
the tuple (name, datatype, value) associated with a
python-registry supports all major datatypes, such as
To open a Windows Registry file, its this easy:
import sys from Registry import Registry reg = Registry.Registry(sys.argv)
Print all keys in a Registry
def rec(key, depth=0): print "\t" * depth + key.path() for subkey in key.subkeys(): rec(subkey, depth + 1) rec(reg.root())
Find a key and print all string values
try: key = reg.open("SOFTWARE\\Microsoft\\Windows\\Current Version\\Run") except Registry.RegistryKeyNotFoundException: print "Couldn't find Run key. Exiting..." sys.exit(-1) for value in [v for v key.values() \ if v.value_type() == Registry.RegSZ or \ v.value_type() == Registry.RegExpandSZ]: print "%s: %s" % (value.name(), value.value())
Advanced users who wish to study the structure of the Windows
Registry may find the
Registry.RegistryParse module useful.
This module implements all known structures of the Windows Registry.

python-registry was originally developed to scratch one of the author's itches. Now he hopes it can be of use to someone outside of his lonely NYC apartment.
As of version 0.2.0, python-registry is released under the Apache 2.0 license. Before that, python-registry was released under the GPLv3.
Nearly all structure definitions used in python-registry
came from one of two sources:
1) WinReg.txt, by B.H., which may be accessed at:
2) The Windows NT Registry File Format version 0.4, by
Timothy D. Morgan, which may be accessed at:
Copies of these resources are included in the
documentation/ directory of the python-registry source.
The source directory for python-registry contains a
subdirectory that contains small programs that use python-registry.
regview.py is a read-only clone of Microsoft Window's
Regedit, implemented in a few hundred lines.
