Ok, so what are you after the bush file editor?
I wrote a winregistry module that does this (for both NT and win9x). It was not really ready for the public, but it worked well with the data that I used at that time. I'm not sure in what condition I left it, and I did not test it with Win7 hives, but maybe we could get its fix for release? If you're curious, I could perhaps dump it in the source element somewhere to work on.
The document I was working from was ntpasswd the well-known WinReg.txt , however I found a lot of flaws in it (it might also lash out at my annotations on that one). Since then, these documents have been prepared, which at first glance can improve the situation.
