guys, I'm not a great fan of the registry cleaners inless they're used prudently
you're best off using these programs to search the reg entries for programs that are no longer on your box, and, rather then the tool that finds dead entries
always use the backup tool when using these programs as well
when yu use the dead entry tool, you are going to find some 400 entries and more.
impossible to check every one of these entries, and then decide if you think it's worth the risk of deleting it
as I say, make sure you use the back up tool, and keep the file for a very long time
sometimes, you won't even know something is not functioning for months
ok
carry on
