Could Not Log on with Primary User Account

Asked By 0 points N/A Posted on -

I own a Sony VAIO VGN FW317J with Windows Vista Home Premium. Yesterday night, I wanted to turn on the light function but pressed F7 by mistake. After that, two choices came up: the first one was about LCD display and the second (which I selected) was something I forgot. Since then, I cannot log-on to my primary user account despite being able to log-on with my secondary user account. Can anyone help me with this? I really need to solve this problem as soon as possible.

Standard F7 key does not really hold any function in Windows. It will only hold functionality when you use Microsoft Word or if you connect your Laptop to an external monitor or Projector. Using Microsoft Word, when F7 is pressed, Thesaurus would open up. If your Laptop/Desktop is connected to another monitor or Projector, it will change the display modes.

You may try to do a system restore back to the date prior to the date of the incident where you accidentally pressed F7. To do system restore, login as the administrator of the computer > Accessories > System Tools > System Restore.

If you have two user accounts on your computer but you can no longer log in to the other one, one way of fixing it is to reset or change the password using the command line. This doesn’t only apply to Windows Vista but to Windows XP as well and I’ve already tried it.

But to change the password of one user account in Microsoft Windows, you need to use an administrator account. To change the password of your user account, click Start, Run then type without quotes “cmd” then hit Enter. In the command prompt window, type the following:

net user [user account] [password]

Where “[user account]” is the user account you want to change the password and “[password]” is the new password for that account. For example:

net user titan pass124

This resets the password for the user account “Titan” to “pass124”. You might encounter a problem when dealing with user accounts that have spaces in it like “The Superior”. In this case, you need to mask the username with double quotes something like:

net user “The Superior” password
