I new help updated to windows 10 from windows 7 get message you are not administrator enter password but nowhere to enter password I am blocked from making any changes can't even reinstall windows I did do the reboot with the shift key and restart key tried choose different options like troubleshooting get to screen that says HomeGroup User$ and asks for password tried to think what it could be not luck.
In a command prompt type "net localgroup administrators" without the quotes. That will tell you the users that are administrators. Do you have users in the administrators group?
Wow. Guest should definitely NOT be in there.
Did you set up a homegroup on your network? I believe the password for the HomeGroupUser $ account would be the homegroup password that was used to create the homegroup. If it is - make sure and create a new user account that is an administrator before you do anything else. Then you can use the new user account as administrator to change your own user account to administrator.
