Project description:
"A Windows-based application I distribute should arrive on each client machine without the usual browser prompt or visible progress window. The objective is a silent background download of a specified .exe so users never see, rename, copy, or otherwise tamper with the file before I’m ready to use it.

Here’s what I need delivered:
• A working proof-of-concept (script, small utility, or embeddable code) that fetches an .exe from a URL and stores it in a chosen directory on Windows 10/11, entirely in the background—no Save dialog, task-bar entry, or pop-up notifications.
• Clear, step-by-step notes showing how to adapt the code to different URLs, target folders, or launch conditions.
• A quick rundown of prerequisites (e.g., PowerShell execution policy changes, required libraries, registry tweaks) so I can reproduce the behaviour on additional machines.

Stability is essential: the download must complete even on metered or throttled connections, and the solution should avoid triggering common antivirus heuristics if possible. If you prefer C#, native Win32, PowerShell, or another Windows-friendly approach, that’s fine—just keep the final workflow straightforward for me to maintain.

Send over your method, compiled binary (if relevant), and the concise documentation, and I’ll test it on my end right away." (client-provided description)
