I downloaded and updated my Windows 7 pro to Windows 10 today. I had two user accounts in Windows 7 before update; Administrator and Ritesh. I never used Ritesh account, so over the time I even forgot that I had this account, and now I don't remember its password. After update to Windows 10, I can see only Ritesh user in login screen. I tried several combination, but they didn't work. I tried going into safe mode, but again it shows only Ritesh user. Setup didn't ask for Microsoft Account during installation, but I did reserve the update using Microsoft Account.
My USB ports are not working so only option I have is CD/DVD recovery.
I tried Reset option as well, but it also asks for Ritesh account verification.
How can I log in using Administrator account as I do remember this account's password?
