my friend had a bad copy of ultimate. He bought a copy today and hd issues changing the product key. He gave me his system and i saw online how to use the run command to do it, however vista is only allowing 4 options, and his firefox browser to be open. no start menu or anything, looks like explorer is not loaded... i tried to type in the new key and it is saying invalid, i did a crack bypass when vista first came out and aparently they caught it, which is why he bought one. any ideas besides reinstalling?
