I use another tool that allows me to exclude that reference in the future.
Which tool is it?
I use RegSeeker - whilst I find it useful - people might not find it very user friendly, not much in the way of in program help. So the user has to have a degree of knowledge, there are also other tools not just the registry cleaner, but it comes with a clear warning '
use at your own risk'.
I believe it does dig deeper into the registry than the likes of CCleaner, which I feel is better if people aren't familiar or comfortable within the registry.
Might not be compatible with later OSes.
