I don't care if the registry is accessed in a different way. Junk is junk, and there shouldn't be junk in the registry. If some one for whatever reason uses the registry editor, he should only find entries that have a purpose, no leftovers from removed software or other junk. I don't have the knowledge to organize the registry, but I'm not claiming to have it. I expect the supplier of the operating system to have that knowledge and to supply us with tools to keep the registry in pristine condition, and not the garbage can it is now.
When Windows NT hit the market, I asked with various known companies if they had a tool to defragment and reorganize NTFS volumes. They all told me that NTFS was so great, you didn't need such a tool. Yeah, sure ...........
I've worked for years with the operating system that was the example for Windows NT (and thus Windows 7, 8 etc.), and at least it is documented in a way that Microsoft can only dream of, and it has all the tools you need to maintain it in the standard distribution kit.
