well i found a way to change wallpaper

You can make an Addon for it to

Make an cmd file and an registry file.
wallpaper.reg
install.cmd In the install.cmd you type the path to your wallpaper.reg
example: install.CMDCODE
regedit /s "%windir%\wallpaper.reg"
After that you edit the wallpaper.reg
Example: Wallpaper.regCODE
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Control Panel\Desktop]
"ConvertedWallpaper"="%windir%\\Wallpaper1.bmp" <- Path to your Wallpaper
"OriginalWallpaper"="%windir%\\Wallpaper1.bmp" <- Path to your Wallpaper
"Wallpaper"="%windir%\\Wallpaper1.bmp" <- Path to your Wallpaper
This is how i did and it works perfectly

After this you create a directory and then select all 3 files..
Wallpaper
.CMD file
.REG file
And then with Winrar, rightclick and
add to archiveWhen winrar popups select
Create SFX archive. After this go to Advanced menu and click on
SFX Options...In the options menu you type the path where it is going to install the files. (
Path to extract)
Example:
CODE
%windir%
And if you look under this menu you se
Run after extractionThere you type path to the install.CMD
Example:
CODE
%windir%\install.cmd
In
Modes menu
where you see
Silent Mode check
Hide allAnd now you are done, make the SFX file
After this make it to an addon with
Add-OnMaker for nLite
