Bought this for my brother who's handicapped, double amputee, hard of hearing, we need for him to have a reliable computer so he can stay in touch with us. After the time is up for tech help with this, he has a message that his windows 10 needs activation that the system if from a pirated copy. This computer stated it came with windows 10. To me, that means it would come with a WORKING SYSTEM.  I did get in touch with the seller, he answered the phone immediately, told me what to do.  We followed his instructions, the computer at this point is working perfectly. Thank you.
