I'm not sure if this is the right tag to be writing about this. I bought an Alienware 15 R2 notbook 2.5 years ago and it came with Windowns Microsoft 10 Home OS. I thought it was a lifetime license but I'm not sure anymore. Since a month ago whenever I turned my notebook on I got a message asking me to activate windows and I do not know what to do. Could someone tell me what I should do? Can Dell fix this or give me another key to activate windows?
