-Here is my Windows solution in the source code exhibit below. It does not do drag & drop, unfortunately. I have taken the original solution **somewhere** from Stack Exchange or somewhere else [^3]. I have had it long time, and lost the link to the original since (apologies for not taking enough care about attributions; I have become better since then). I have revisited and cleaned it in the new year with my renewed knowledge in Elisp coding.

     I can't do it, but if you know how to do it, probably you could do all sorts of good things with it (e.g. you can save the image in a different format [^2]). 
 
-   One thing: In the main function, `powershell` appears twice in a row. It is not redundant. I have no idea why, but it needs to be there twice [^1]. I tried to make it do with only one, but the image was not correctly stored. I would appreciate it if someone with more knowledge can enlighten me with the way PowerShell works.

-[^1]: I suspect it is related to the fact that the default shell in Windows is set to `cmd` rahter than PowerShell with variable `w32-system-shells`; that is, the `shell-command` in Emacs launches `cmd`, and then within it our command string tells it to launch `powershell`. However, this still does not explain why it needs the second `powershell` command, because wihtin PowerShell, or even in `cmd`, you don't need to do it. I will leave it as it is for now. It works with the current default PowerShell version 5.1 that comes with Windows 10. The script itself works wtih PowerShell 7 that I have separately installed, so it should be fine for a long term.

 [^2 ]: I have also confirmed that `[System.Drawing.Imaging.ImageFormat]::Png` is not really needed. Without it, PowerShell still saves the image as PNG **no matter what extension you gives to the method**. You can, nevertheless, tell it to save the image file in a different format. For example, `[System.Drawing.Imaging.ImageFormat]::Tiff` or `[System.Drawing.Imaging.ImageFormat]::Bmp`. Refer to [Microsoft's documentation](https://docs.microsoft.com/en-us/dotnet/api/system.drawing.imaging.imageformat) for other accepted formats.
