The issue is that win32 api can't handle names with embedded null characters. That's certainly an issue when it comes to registry keys, because such keys are not deletable by OS shipped registry tools.

Here's the more complete description; http://reboot.pro/files/file/232-regkeyfixer/

Code for PoC to create invalid keys are attached as CreateInvalidKey.au3

Code for the tool to fix these keys are attached as RegKeyFixer.au3

Option for recursive search is on the todo list.

Made some changes to it, like recursive search and modification, as well as including another PoC that will create a different set of registry keys proving to be somewhat impossible to handle: http://www.mediafire.com/download.php?65gcjxvtln291yx

Let me know if you figure out how to deal with those tricky long named keys. I certainly did not..
