I recently ran updates on one of my clients computers, and during the reboot after putting in their login crediantials windows said that it needed to be activated. After clicking ok, it just says windows is already activated and I was stuck at that screen. Tried everything to access this computer, but decided to just rebuild the computer. Now why would this have happen? I also ran magic jelly bean on other computers in the office, and they are reporting different keys than the stickers on the computer. Their reporting SLP OEM Keys, which were found using google. Why would someone use SLP OEM Keys? Is it ethical/legal? Are you able to run updates on SLP OEM Keys?
