VBS file to modify registry

Posted on 2008-10-31

I am looking to create a simple .vbs file that will modify a registry key. I need it to have a prompt to change one key, and automatically change the other key.

The keys are
hkey_local_machine>software>microsoft>windows nt>winlogon>defaultusername
hkey_local_machine>software>microsoft>windows nt>winlogon>defaultdomainname

I need a simple prompt that will ask me for the defaultusername, and when I enter it, it will change the key with my value. And, I need it to always change the defaultdomainname to "MCPS".

I have never programmed, and I am not even sure if this is the correct way to do this. Thanks for your help!

Here is the script you requested. Let me know if you have any questions.
Const HKEY_LOCAL_MACHINE = &H80000002
Const cTitle = "Change Registry Values"
strComputer = "."
Set oWS = CreateObject("wscript.shell")
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _ 
    strComputer & "\root\default:StdRegProv")
 
 
sKeyPath = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"
sValueName = "DefaultUserName"
sDomain = "DefaultDomainName"
sDomainValue = "MCPS"
Do
sValue = InputBox("Please type in the DefaultUserName registry value you want to use:", cTitle, "(Enter value)")
	If sValue = "" Then
		sRes = oWS.Popup("Sorry, you must enter the DefaultUserName reg value to continue." &_
		" Do you wish to try again?", ,cTitle,vbExclamation+vbYesNo)
			If sRes = vbNo Then
				oWS.Popup "User canceled, Exiting script!", , cTitle, vbInformation
				WScript.Quit
			End If
	End If
Loop Until sValue <> ""
 
oReg.SetStringValue HKEY_LOCAL_MACHINE,sKeyPath,sValueName,sValue
oReg.SetStringValue HKEY_LOCAL_MACHINE,sKeyPath,sDomain,sDomainValue
 
oReg.GetStringValue HKEY_LOCAL_MACHINE,sKeyPath,sValueName,sValue2
oReg.GetStringValue HKEY_LOCAL_MACHINE,sKeyPath,sDomain,sDomainValue2
 
If sValue <> sValue2 Or sDomainValue <> sDomainValue2 Then
	oWS.Popup "There was a problem in changing the registry values," &_
	" please check that you have enough rights to write to the HKLM of the registry", , cTitle, vbCritical
Else
	oWS.Popup "Registry values were changed successfuly!", , cTitle, vbInformation
End If

Although hubasan's code appears to be correct, I would HIGHLY advise you not do this.  Storing default domain/user/password information in the registry is a big security hole.  That means that booting the computer (by anyone) will log it in and then the user could navigate to that key to get the users's password.

I realize that you can't do this with vbs, but it's a better setup to use xp power toys to do your auto login as it won't store the PW in cleartext.

the script does NOT have a password to be stored in the registry. the user will still have to enter their password, but the username and domain would be filled in for them.

I BELIEVE... the defaultusername and defaultdomainname are only used for auto login when the autologin flag is set.  I believe that the defaultusername and defaultdomainname will still always display the last logged in user.  

But I could be wrong.
