It’s very different. Can I open a PDF from Windows into Windows Sandbox with 2 clicks and close with 1 after reading, nearly instantaneously, without noticing the virtualization? Nope. Windows Sandbox is just a fresh VM, almost useless.

You can do exactly that. Setup a .wsb file that mounts your downloads folder to the VM desktop and disable network.

Open the .wsb (1 click) then open the PDF (1 or 2 clicks). When you're finished close the windows sandbox window and it'll all be gone.

Using a zero install PDF viewer, the wsb login command and a few lines script file one could also have the PDF automatically open in the Windows sandbox with a double click or using "Open with" from the context menu.

If you're on Windows, and you want to download something, install it, see what its all about.

Windows Sandbox starts in like 8 seconds to be usable and is trashed when you close it.

So its far from useless.

But for your usecase, yes it wont work.
