Unable to logon after changing from domain to Workgroup

Hi jparikh, Welcome to Windowsbbs!

Since you are not able to login using the current user try logging into the administrator account. To do this, on the welcome screen press Ctrl, Alt, Delete twice on the keyboard. You should get a logon window asking to put in the username and password. In the username box type administrator. In the password box type whatever password was used to log into the administrator account. If there was no password then leave the password box blank and hit ok to login.

Once you login to Windows create a new user account with administrator privledges and use that account for using the PC.
