How to reset Windows Seven password

[riteshtechie]

I am looking forward to reset password of Windows Seven by my app.

Using command

net user user_name *

But I don't know how to run this command

process.start("net user" & user_name & "*")

gives error.


So how to do that or is there any other direct command which can change/reset windows password.

[Hack]

How about using the tools provided by Windows 7?

process.start("net user" & user_name & "*")

Try this with appropriate spaces...

process.start("net user " & user_name & " *")

Note: I am assuming that you are the administrator....

The system cannot find the file specified

The first command you're sending, isn't a command. It's supposed to be the file name. So when you send, "net user", your application is looking for something to launch either in the SYSTEM PATH or the path of your application, called "net user."

Chances are, you want to send this command with the command window, correct?

If so, you'll need to do something like this:

Dim p As New Process
p.StartInfo.Arguments = "<arguments you would type into a command window>"
p.StartInfo.FileName = "cmd"
p.Start()
p.Dispose()

Normally, you'd also need to specify the FilePath, but since the command window is located in the SYSTEM PATH, that isn't needed.

Also, as previously stated, you need to be have administrator privileges in order to reset a windows password. Also, process needs to be elevated in order for net user to work.

In order to elevate the process, you'll need one more line of code. It will be a StartInfo object called Verb. You'll need to pass a string to it called runas. I'll leave it up to you to add it in there.

@weirddemon

But this one also doesn't help all it does is it opens Command Prompt and thats it, no argument were passed using this method.

[weirddemon]

Then you're doing something wrong.

Post the exact code you're using.

[riteshtechie]

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
 
        Dim myReg As String = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "RegisteredOwner", Nothing)
        'MsgBox(myReg)
 
        Dim p As New Process
        p.StartInfo.Arguments = "net user " & myReg & " *"
        p.StartInfo.FileName = "cmd"
        p.Start()
        p.Dispose()
 
     
   End Sub

[weirddemon]

Well, first, if you really want to use the registry to get the current user, you can. But VB .NET provides a method for that: Environment.Username.

Second, as I mentioned, you need to elevate the User permissions. But, I'm only guessing about that being the issue.

So, I need to know what's showing up in the command box. Nothing at all? No text whatsoever?

[weirddemon]

Actually, I looked into it, and it's not working... which is odd. There might be an an alternate method used for the command window. I'm looking into it.

Yeah I am too looking for that thanks for helping me

[Megalith]

curious why you would reset the windows 7 password? i can think of 2 reasons:- your password is changing (a virus perhaps?) or you have a validation issue with your license.

[riteshtechie]

^ neither of the above two I am creating an application which give user the flexibility to reset password in 1 click.

[riteshtechie]

any ideas

[weirddemon]

I'm thinking you'll need to use SendInput. In which case, you'll need to use RedirectSnedInput from the StartInfo object.

I don't have time to look at it, but if I do tonight, I will.
