How can I create a registry file for xp to change desktop backgrounds to a batch file or vbs script?

Recently I have been able to push a batch script to change the desktop background in GPO policies for each workstation through the server

This is the batch file:       copy \\server\sharename.jpg C:

Also, I put the same UNC above in the GPO: Administrative Template, Desktop, Active Desktop, Active Desktop Wallpaper and Enabled Active Desktop.

This works fine, all workstations/ users get whatever desktop I want them to get but, the desktop icons do not use drop shadow. Therefore the icons do not blend with the desktop. Locally on a workstation I could right click on My Computer , Advanced, if it were not if my restrictions on each workstation/user I would be able to Performance Settings, Visual Effects, Custom, Selec/Check use drop shadows for icon labels on the desktop. Usually that does the trick but when I modify GPOs I longer can choose this option or it does not work.

Hey,

The attached VbScript will take the wallpaper defined at the top, copy it to the client (into C:\documents and settings\somebody) and set it with a few parameters described in the comments.

The file should be bmp, anything else will fail to set when the script runs UpdatePerUserSystemParameters. I believe because it performs an implicit conversion when you set a jpg through the GUI.

HTH

Option Explicit
 

' Network and local locations for the wallpaper file

Const WALLPAPER_SOURCE = "\\servers\share\wallpaper.bmp"
 

Sub SetWallpaper

	' Copies and sets the client wallpaper
 

	Const REG_HKCU = &H80000001
 

	Dim objShell, objFileSystem, objFile, objRegistry

	Dim strWallpaperDestination, strKeyPath, strCommand
 

	' Get the current user profile so we can copy the wallpaper there.

	Set objShell = CreateObject("WScript.Shell")

	strWallpaperDestination = objShell.ExpandEnvironmentStrings("%USERPROFILE%")
 

	' Get the wallpaper file from the source

	Set objFileSystem = CreateObject("Scripting.FileSystemObject")

	Set objFile = objFileSystem.GetFile(WALLPAPER_SOURCE)
 

	' Update the destination path to include the file name

	strWallpaperDestination = strWallpaperDestination & "\" & objFile.Name

	objFile.Copy strWallpaperDestination, True

	Set objFileSystem = Nothing
 

	' Connect to the Registry on the local machine

	Set objRegistry = GetObject("winmgmts:\\.\root\default:StdRegProv")
 

	' Set the values for the Wallpaper

	strKeyPath = "Control Panel\Desktop"

	objRegistry.SetStringValue REG_HKCU, strKeyPath, "Wallpaper", strWallpaperDestination
 

	' Set the Position to Stretch

	objRegistry.SetStringValue REG_HKCU, strKeyPath, "TileWallpaper", "0"

	objRegistry.SetStringValue REG_HKCU, strKeyPath, "WallpaperStyle", "2"

	Set objRegistry = Nothing
 

	' Update the system settings (refresh)

	strCommand = "RUNDLL32.EXE user32.dll,UpdatePerUserSystemParameters"

	objShell.Run strCommand, 1, True

	Set objShell = Nothing

End Sub
 

SetWallpaper

Chris Dent: Thanks but, I wanted to ask
I  just added this to your script. I don't see anything else to modify.
' Network and local locations for the wallpaper file
Const WALLPAPER_SOURCE = "\\server1\pic\ NYC.bmp"

Chris Dent:
Do these lines apply to what I am doing
' Get the current user profile so we can copy the wallpaper there.
      Set objShell = CreateObject("WScript.Shell")
      strWallpaperDestination = objShell.ExpandEnvironmentStrings("%USERPROFILE%")

And

' Connect to the Registry on the local machine
      Set objRegistry = GetObject("winmgmts:\\.\root\default:StdRegProv")
 
What I want to do with this script is put it in my logon script in Group Policy (maybe change the picture file name and extension to bmp like you said), \\server\sharedfolder\pic.bmp for different groups and put the scripts in different OUs so whoever gets the script at the workstation the desktop background would change for different users. My problem is the background icon desktop shadow does not work when I use the batch file eventhough it works well otherwise.

I just trying if I apply to xp registry the background and icon would show correctly.

> maybe change the picture file name and extension to bmp like you said

Open with MSPaint and save as .bmp. Changing the name won't change the format and even though it stop picture viewers opening it normally.

> strWallpaperDestination = objShell.ExpandEnvironmentStrings("%USERPROFILE%")

Just expands the User Profile environmental variable as a safe place to copy the wallpaper to without requiring admin rights. You can see the contents by typing this into the command line:

echo %UserProfile%

>       Set objRegistry = GetObject("winmgmts:\\.\root\default:StdRegProv")

Simply a connection to the registry on the local machine (dot is the local machine). It's how the script sets the wallpaper.

I'll take another look at that setting at home.
