Can anyone recommend a good (and ideally free) Registry Search & Replace tool? There seems to be a lot of utilities that searches the registry, but not very many that does the replacing. I've found some really old ones (from the late 90s to 2007). I was hoping for newer ones or ones still maintained. I did run across RegReplacer, but that one doesn't seem to work very well (It only found 2 instances of a string where NirSoft's RegScanner caught 449).

I also found Registrar Registry Manager via this question here, but it's $44 :-\
