[rbt]

On windows xp, is there an easy way to extract the information that
Python added to the registry as it was installed?

Using regedit.exe, look at the registry keys and values under

HKEY_LOCAL_MACH INE\Software\Py thon

If you need to know how to read the registry from Python: please install
the python win32 extensions (or use ActivePython).

There's more to it than that... isn't there? I've used _winreg and the
win32 extensions in the past when working with the registry. I thought
perhaps someone had already scripted something to extract this info.

I'm creating a Python plugin for Bartpe (Windows Pre-Install
Environment) and it works OK, but to make it work _exactly_ like it does
on XP (.py and .pyw associate with python and pythonw), I need to
extract the reg entries so I can recreate them in the WinPE environment.

Thanks!

Ok, if you need to get all changes in the registry, you can use regdiff.

Take a snapshot before and after installing Python. However, this is not
a wise approach.
For example:

1. One can have a system drive 'C:\' others 'G:\'
2. One can have Windows installed in \Windows others in \WinNT and
others in \MyWinNT
3. For many registry values, you cannot really tell if you need to
correct a value or not.

As a result, I believe you will only be able to use the 'regdiff' only
on the same type of computer, with the same system drive, same system
directory, same windows version etc. For other computers, there is no
guarantee for that it will work.

Yes, a small firm named Microsoft has done this (but not tested w/2.4):

That tells me this:

Caption: Registry

Description: Registry

Maximum Size: 54
Name: Microsoft Windows XP

Proposed Size: 54
Status: OK

You should be able to find all the entries in msi.py that's used to build the
installer.

Actually you don't need the PyWin32 extensions to read the Windows
registry since the _winreg module was added to the Python core.

If it's just a matter of creating those associations, I believe you can
do that equally well using the "ftype" and "assoc" console commands, via
os.system() or something similar.
