Hi, I'm trying to figure out a good method to convert from authentic OEM Home Premium to authentic OEM Business without reinstalling. I've successfully used VOATK to convert to Business and then activated with authentic Business key, but even thought Business exclusive features work (like joining a domain) the OS still says it is Home Premium. While this is basically a cosmetic issue, is there any way to complete the transformation from Home Premium to Business? Thank you, Aris
