Upgraded from 7, system has two identical Samsung screens, os only recognized right screen. Reloaded vid card driver. Os booted to left screen, but went to device user screen, selecting a user that had not used system for three years. Do not have that users pw. The user name is the name on Microsoft account. Did not create not disk on first start up of 10. I read the 8.1 fix for this does not work on 10. ???
