I had to delete all files off my computer when I left a company I worked for, but in the process lost the inital domain sign in and cannot log into my computer at all. When I restart the Log on to Windows screen pops up asking for the User name and Password, but the log in I used before (my company infomation) is no longer working. When I "sign in" it says "the system could not log you on make sure usernameand domain are correct then typer the password again. letters and passwords must be typed using the correct case" Is there a way to bypass this? How do I get back into my computer?
