I can not login to any account on my HP computer because Windows tells me "It must be activated before I can login to an account." I'm given the option of "Yes" and "No".
When I click "Yes", It says "Windows is already activated.", and I click on "Ok". But when I try logging in, it tells me I still need to activate. When I click "No", it doesn't do anything. It just logs off. How can I fix this?
