Crusing for Registry Interface Classes for use in win32 C++

I am looking at drragging some old c-ish win32 class that handles my registry IO forward into the current century. My option is either to re-write it, test, debug..etc or find some code that has the job done already.

My criteria would be:

STL aware ( at least for reasonable string type handling )
Fairly modern C++
Not include dependencies for stuff I don't use/want/have (MFC, Managed, .NET, ATL, etc)
Sane Exception design.
Unicode aware or at least cleanly written.
Secure use of std c functions. (_s variants)

My survey of the options is:


http://www.codeproject.com/Articles/14508/Registry-Manipulation-Using-NT-Native-APIs
This is much more functionally complete but needs a complete re-write.  While interesting in that it uses the NTAPI calls.  The Unicode handling is a mess and needs a re-write along with the general structure and error handling philosophy.

This is fairly rudimentary and uses the Win32API calls. (RegCreateKey etc)
No maintenance since 1999

Looks like early Windows Classes Style of code. 
No maintenance since 2003

http://www.codeproject.com/Articles/2916/CRegSettings-registry-helper-class
Written in a kind of C meets MFC style. Very Quick and dirty.

Written in old school MFC/ATL style Macro madness. Nice work back in the day but a pain to maintain or use going forward.
No maintenance since 2004.

http://www.codeproject.com/Articles/10729/A-nother-C-Registry-Wrapper
Written in fairly modern c++. STL aware. Unit tests of some description.  All Win32API, fairly simple design.

This is an interesing style.  Seems to be fairly simple in terms of functionality. Written in older Win32 style with error codes and error flags rather than exceptions. Basic use of templates.

 This looks nice.

Registry wrapper with encryption. Interesting but overkill for my needs.

Yet another "simple" wrapper for the Registry. Pre STL and very old school. Not Unicode compliant.
No maintenance since 2000

http://www.codeproject.com/Articles/1031/A-Registry-Class
A bit old school but well written.
Some comments posting fixes in 2009 for Unicode issues.

Looks a bit MFC style. Some bugs in the comments.

Uses templates so there is some hope.  A bit dated as far as functionality goes.

Looks like a simple read/write wrapper.

No information that I can find about this.

Very basic functionality. Looks like write only.

Looks nice, smells nice. Nice.

I think my search is over.  This is current generation code and frankly there is nothing better out there that I can turn up in this time.  I'm done.
