• Windows 8 or higher
• MPV video player installed

If MPV is not installed, you will encounter the following error:

Error: Your system does not have a valid video player (MPV) installed.
Please install it using the following command:
$ choco install mpv
If you have never used Chocolatey or installed a package with Chocolatey,
please see the following guide: https://dev.to/stephanlamoureux/getting-started-with-chocolatey-epo

Skip if you already have MPV installed.

1. Open a new PowerShell window with admin rights.
2. Snippet from Chocolatey Documentation:

With PowerShell, there is an additional step. You must ensure Get-ExecutionPolicy is not Restricted. We suggest using Bypass to bypass the policy to get things installed or AllSigned for quite a bit more security.

• Run Get-ExecutionPolicy. If it returns Restricted, then run Set-ExecutionPolicy AllSigned or Set-ExecutionPolicy Bypass -Scope Process.
• Now run the following command:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

1. After installing Chocolatey, open a new PowerShell window with admin rights.
2. Run the following command:

choco install mpv

1. Download the latest release from the releases page and save it in a secure location.

2. Open CMD in the directory where the file is saved.

To simply set a video as your wallpaper:

ElyWE --set "<video path>"

To add a right-click menu option for video files:

ElyWE --install

After installing, you can right-click any video file and select "Set as desktop background".

To remove the right-click menu option:

ElyWE --uninstall

To enable ElyWE to start with Windows:

ElyWE --enable_startup

To disable ElyWE from starting with Windows:

ElyWE --disable_startup

ElyWE --quit

Sometimes, ElyWE will be flagged as malware by several anti-virus programs (Avast, AVG, Norton, McAfee, Windows Defender, etc.), this, however, is a false positive.

3 things cause this to happen:

a) Because the program executable isn't signed

b) Some antiviruses detect this as a joke program

c) Writing to registry keys and starting up with Windows seems suspicious.

If downloaded from my GitHub, the program is safe to use (i cannot give this promise if you download it from somewhere else!). It is okay if you do not trust me; you can always go ahead and compile it yourself.

Please note: This software is intended for demo purposes, not for productive use. As such, it is not polished, well-written, configurable, or in any way convenient to use. Do whatever you want with it, at your own risk.
