Re: Regedit "Error while opening key"

Bart's PE would work if this was a problem with the host or VPC
install, but it's not. Neither install is infected.

The problem, in fact, is the Win32 API used by REGEDIT, which can
view, but cannot manage, registry key names with embedded nulls. (It's
amazing how little info there is about this problem in the MS
newsgroups.)

The nature of the problem is described here:
http://www.sysinternals.com/Information/TipsAndTrivia.html#HiddenKeys

This link will also work: http://tinyurl.com/azzto

The "RegDelNull" tool will allow the null-containing entries to be
deleted. It can be downloaded here:

http://www.sysinternals.com/Utilities/RegDelNull.html

.... but MS should provide a better command-line tool that allows the
key and/or name/value pair to be fully managed.

Better, MS should prevent such data from being written to the registry
in the first place in all Windows versions. (IMHO, that's precisely
what the OS is for.)
