Ekka,
Technically you have 3 Desktops (login screen, lock screen & the normal Desktop)
You can use the following policy keys to enable Desktop Wallpaper change:
Current User:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDeskt
op
All Users:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesk
top
Key Name: NoChangingWallpaper
Key Type: DWORD
Value: 0 = allow wallpaper change, 1 = disable
Key Name: NoHTMLWallpaper
Key Type: DWORD
Value: 0 = allow HTML wallpaper, 1 = disable HTML Wallpaper (BMP only)
You can also specify centered/tiled/stretched... here:
Current User:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
Key Name: Wallpaper
Key Type: STRING
Value: path to bmp ("C:\SomeDirectory\SomeFile.bmp)
Key Name: WallpaperStyle
Key Type: STRING
Value: 0 = centered, 1 = tiled, 2 = stretched
If you want the SAFE MODE wallpaper then you can change like so:
Current User (only):
HKEY_CURRENT_USER\Software\Microsoft\Internet
Explorer\Desktop\SafeMode\General
Key Name: Wallpaper
Key Type: STRING
Value: path to wallpaper ("C:\SomeDirectory\SomeFile.htt) etc
You can also take things one step further and specify the lop left pixel to show
picture:
Current User:
HKEY_CURRENT_USER\Control Panel\Desktop
Key Name: WallpaperOriginX
Key Type: STRING
Value: in pixels (100 for example)
Key Name: WallpaperOriginY
Key Type: STRING
Value: in pixels (100 for example)
If you want to change the LOGON wallpaper then you can here:
Key Name: Wallpaper
Key Type: STRING
Value: path to bmp ("C:\SomeDirectory\SomeFile.bmp)
Key Name: Pattern
Key Type: STRING
Value: "(none)" - include brackets too surrounding none
Key Name: TileWallpaper
Key Type: STRING
Value: 0 = dont tile...
I hope this helps,
