I ran across the exact same thing just yesterday. I will not, however, go back on my OS. The other piece of advise I got was to use Zortam ID3 Tag Editor, which isn’t practical because I’d have to purchase it in order to use it for any length of time. I’ve scoured the registry and all the *.cfg, *.inf, *.ini, and another files I can get my hands on to try to remove the old user information, but haven’t been able to find a thing.
Any other ideas?
