Good question.
My advice is first, if you're not experiencing the issue, obviously there's no need to do anything.
As far as Windows Updates go, I would advise keeping up with them. It appears I've identified the TD issue, and the workaround works, so there's no good reason NOT to install Windows updates. If you experience the problem, use the "reg" file to fix it. This is a good *workaround* because it can easily be undone if necessary. It is not the solution to the problem.
I am still investigating the issue. I have a version 2.5.5 ready for some testing but I'm not quite convinced it is the proper fix, so I have not yet released it. And of course, the holidays are currently delaying that just a little bit. Stay tuned ...
