BC Adviser was kind enough to help me with viruses in my old Dell Windows Vista Laptop in another topic.
I was trying to change my sign in or log on password. It became somewhat difficult when I needed to get into the Administrator level account first. When I started to see this information my computer said some files were contaminated. That had me stop. I went into start and then wrote, Computer Management, and opened it. Microsoft site stated to type in cmd in the Start search box and then press Enter, but I was unable to get past that. I don't believe I did any damage because the operating system seems fine.
I would surely appreciate any help trying trying to change the Log in or Sign in Password.
