Does anyone know of a way to replace the img01.jpg (desktop wallpaper) in starter?
if u mean the logon screen :
6th post down...
if you just mean the desktop wallpaper :
rightclick desktop, then adjust to personal looks, then choose desktop wallpaper at the bottom, here you can change the wallpaper...
At last report, not possible due to a hash check built into the system.
If you replace that file, you'll supposedly get a black screen. Not sure if that means you could actually just do a black background, or if it's essentially putting the unit into reduced functionality mode.
But at least so far, it does appear to be hardwired into the starter edition (which I think is only coming on netbooks for the time being).
R U sure? I would remind that if you go in the registy to: (but it only works with OEM Version)
1) go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Authenication\LogonUI\Background
2) there must be on the right side the Value OEMBackground. WHen its there follow with STep 4
3) create it with: New | DWORD-Value)
4) double klick it and change the Value to 1.
5) WIndows uses the file: "backgroundDefault.jpg" as background picture. For special resolutions there are files like : "background 1280x1024.jpg"
6) When you have the file: Watch out! The max. size for the picture is 256 kb!! WHen you need it, put the quality of the jpg file lower.
7) You need to open the Windows Explorer with Admin Rights (can be done if you type in the searchmenu "explorer" and then rightclick it and open with admin rights
8) Then navigate to Windows\system32\oobe\info and rightclick it.
9) Choose "Properties" and go to "Security".
10) Activate the option "allow" in the row "Full Access". Then click ok. Then click yes.
11) The preworked jpg file are going to be put into the OEM Directory. It is always: Windows\system32\oobe\info\backgrounds (afaik)
12) When you restart your Windows 7 it should show up your new Login Background =)
I'm pretty sure that's correct... however
All you need to do is find the file that has the check, determine what kind of check it is (CRC32, MD5, etc), get the value for your new file and replace the 'good value' with the new one.
Easier said than done, but doable.
Alternatively, you could possibly just disable the check, like UXTheme does.
That's for the logon screen. Not the desktop background.
And it's not just the OEM version. Non OEMs will at worst need to make the folder, though I believe as soon as you change the registry values or during next restart, it is created.
I hope that someone with such knowledge will find the way and make a patch for this problem.
I'm workin on is since I found the first RTM version of it, but atm it is hopeless...
And I'm now give it up.... =(
As for the technical side, a new licensing bit was introduced ChangeDesktopBackground-Enabled. On Starter Edition Editions, this bit is set to 0, disabling background setting capabilities (in e.g Windows Photo Viewer and the Display/Theme Control Panel applets). The infection goes deeper into system files shell32.dll and themeui.dll too, hard-coding the wallpaper to %windir%\web\wallpaper\windows\img0.jpg.

img01.jpg is desktop background not logon background
this is what he is trying to change afaik.
so my guess is that if he can dump what this code is doing he will be able to edit the dll's and mod them
I thins home basic has exactly the same functionality as starter, but you can change the background, so you ould just use that
