Microsoft Network Password Prompt

After disconnecting the network setup, within a home environment, (network is not available now) the password prompt comes up every time i reboot! I no longer need this prompt! Its a royal pain…how do stop the prompt from appearing every time i turn the system on? i have unchecked every possible network link for the file sharing, i was tasked with. the exception is – i have high speed cable connection. (the prompt was not there before i started the file sharing)
