I just read through this and I came away impressed. Not a bad article at all and having a backup of ones registry is well, just smart!
This is a really good article.
Most folks use the 'Find' command from the Windows Search box (solid way to do it). But, you can also use the 'Find' command from the command prompt and if you use Windows Server Core, this is a VERY thing to know.
So, I have to preference this with a little caution. I am not saying this is a "true" fix. Sometimes you simply have to re-make the profile. That usually works the best. But, if you want to try this "fix" first, this might be something that works for you. It did for me, thus the reason I am posting it.
