  • How to replace or change the administrator password.

    Original title: I've got a helping hand me down from the laptop. The previous owner was also the administrator. She forgets all THE passwords.

    Please help if you can tell me how can I know or overide the administrator password and the password of the office she now had on users page where you select the user who will use the laptop. As you can see, I'm not computer very warned, I am on SSI and was thrilled to have the laptop to help me but I can't get the passwords I need to help remove, install or difficulty of the programs, files and as I manage problems. I try to install or uninstall something or the computer tells me that I have to do something and then the administrator password is necessary. I went to the Helpdesk and they were very useful for what they could do for free and it can all work but I can't access anything until I can log on to the Office of the administrator first, then do as I was directed by Microsoft Help Desk. Anyone who could help me I would be happy because I can't afford to take it to a professional. And I have no idea how to get around the administrator passwords. I looked for administrator password forgotten, but he did not come. I need to access any of the password for the administrator Office, and then I could get into some other areas or try the Help Desk tells me. Or if anyone knows how to do all this, I had like to hear on your part, thank you.

  • I need to change the administrator password

    My husband was the administrator of our computer and he died in June.  I don't know what it is.  I never needed to know because he took care of everything.  How to change or find out what it is.  The system restore disk will do it

    Hello

    The system restore disk will not help you find the password. Unfortunately, you cannot change the password without knowing the administrator password. If you have another
    account administrator on the computer, then you can log in to that account and change the password from there. Since you have a restore disc, you can reinstall Windows and
    start all over again.

  • Receive the Error Message "the user profile Service could not connect. Cannot load the user's profile' trying to change the administrator password

    Original title: how to change a password for an administrator account that does not work properly?

    When I try to change the settings for an account via the Control Panel, I get the admin password, but nothing happens. Close the popup box, but the program I want to open do nothing. I tried to change the password itself on the administrator account, but when I try to log on it, the message that appears is "the user profile Service could not connect. User profile cannot be loaded. "So far, I have not found a way to change the admin password or even that the password works. I tried to remove the program responsible for Parental control in the Task Manager, but it is too safe for me to enter. Is it possible to restart the Parental control or the account administrator if I can't access?
