I am not able to make any changes to my user accounts, can't add accounts ( when I attempt to add an account I receive the message" the specified account name is not valid because account names cannot contain the following characters" even though none of the specified characters have been used), can't change administrator etc....,
-I have tried enabling the hidden admin account by using (net user administrator /active:yes) I have done this under the elevated command prompt as an administrator as well as in safe mode with the same result: "access denied" "system error 5 has occurred" I get the same response when trying to add a new user account through the elevated command prompt.
-I have tried enabling the default admin account through winre using method II. I enter the registry editor=go to hkey_local_machine=load hive=enter config=When I choose the SAM file and click open I receive the message "this file is in use. enter a new name or close the file that's open in another program"
