Write a batch script for windows 10 which download an image from a given url and set it as wallpaper
Here is a batch script that downloads an image from a given URL and sets it as the wallpaper on Windows 10:
```
@echo off
set url=https://example.com/image.jpg
set filename=image.jpg
set wallpaper_path=%USERPROFILE%\Pictures\%filename%

powershell -Command "Invoke-WebRequest -Uri %url% -OutFile %wallpaper_path%"

rundll32.exe user32.dll,UpdatePerUserSystemParameters 1, True, %wallpaper_path%
```
Let me explain what each line does:

1. `@echo off` - This line turns off the command echoing, which means that only the final output will be displayed in the command prompt.
2. `set url=https://example.com/image.jpg` - This line sets the URL of the image to be downloaded. Replace `https://example.com/image.jpg` with the actual URL of the image you want to download.
3. `set filename=image.jpg` - This line sets the filename of the downloaded image. You can change this to whatever you like.
4. `set wallpaper_path=%USERPROFILE%\Pictures\%filename%` - This line sets the path where the downloaded image will be saved. The `%USERPROFILE%` variable points to the current user's profile directory, and `Pictures` is a subfolder where the image will be saved.
5. `powershell -Command "Invoke-WebRequest -Uri %url% -OutFile %wallpaper
Write a batch script for windows 10 which download an image from a given url and set it as wallpaper.

Here's a simple batch script that uses PowerShell to download an image from a URL and set it as the wallpaper. Save this script as `setWallpaper.bat`:

```batch
@echo off
setlocal

:: Define the URL of the image
set "url=https://example.com/image.jpg"

:: Define the path to save the image
set "savePath=%temp%\wallpaper.jpg"

:: Use PowerShell to download the image
powershell -Command "(New-Object System.Net.WebClient).DownloadFile('%url%', '%savePath%')"

:: Set the downloaded image as the wallpaper
reg add HKCU\Control Panel\Desktop /v Wallpaper /t REG_SZ /d "" /f
reg add HKCU\Control Panel\Desktop /v Wallpaper /t REG_SZ /d "%savePath%" /f
RUNDLL32.EXE user32.dll,UpdateIniFile -ini user.ini Wallpaper

:: Clean up temporary file
del "%savePath%"
```

Replace `https://example.com/image.jpg` with the URL of the image you want to download.

To run this script, open Command Prompt (cmd) as an administrator and navigate
