Change Another Users Wallpaper (W2K)

[linuxstudent]

Hey does anybody know if it would be possible and if so how to change another users wallpaper in windows 2000 via the registry without knowing their login information?

You can if you have administrator permissions, by changing the value in the desktop key under their SID. e.g. [HKEY_USERS\[USER SID]\Control Panel\Desktop].

So here is a VBScript i wrote to do just that. It writes the wallpaper to ALL login acounts including the .DEFAULT. Hope this helps!

Const HKU = &H80000003 '//HKEY_USERS

Set WshShell = WScript.CreateObject("WScript.Shell")
Set oReg = GetObject("winmgmts:!root/default:StdRegProv")

SID = enumkey(HKU, "")

For s = 0 To UBound(sid)
If InStr(SID(s),"_Classes") = 0 Then
WshShell.RegWrite "HKEY_USERS\" & SID(s) & "\Control Panel\Desktop\Wallpaper", "%windir%\BGInfo.bmp"
End If
Next

Function EnumKey(Key, SubKey)
Dim Ret()
oReg.EnumKey Key,SubKey, sKeys
ReDim Ret(UBound(sKeys))
For Count = 0 to UBound(sKeys)
Ret(Count) = sKeys(Count)
Next
EnumKey = Ret
End Function
