I replaced Run with Search using your reg file on my Dutch OS. That worked fine, I got Search back (in Dutch). Then I changed my mind and decided to put Run back, using your restore file. This failed: I now have neither Search nor Run in the right dark side.
General question: Is it safe to use the register edits on a non-English OS? Specific question: Is there another way for me to get Run back?
Thanks, by the way, for your very clear and useful tutorials.
