Windows 10: How to Change Wallpaper automatically with Task Scheduler

I tried making a script in task scheduler that would automatically change my wallpaper. Here is the script which i saved as a .vbs file for task scheduler to run:

dim shell

Set shell = WScript.CreateObject("WScript.Shell")

wallpaper = "C:\path\to\wallpaper.jpg"

shell.RegWrite "HKCU\Control Panel\Desktop\Wallpaper", wallpaper

shell.Run "%windir%\System32\RUNDLL32.EXE user32.dll,UpdatePerUserSystemParameters", 1, True

The script is from this forum post if you want to check it out.

Problem is, when I run the task all that happens is that a window comes up and asks "How do you want to open this file?". How do I fix this and make a task that I can set to change my wallpaper on a specific schedule?

Also, I know about DisplayFusion and other 3rdparty programs. But I don't want to use these, so no need to suggest programs that do this.
