AFAIK you don't need to install emacs on Windows, you just can unzip the binaries you can download on the official website on any folder, even your desktop, and run the EXE file on the \bin folder, without the need of admin privileges.

True, but that would certainly be against the "spirit" of their policy. It crossed my mind, though.

What about something like https://vscode.dev/

It runs a lighweight copy of vscode entirely in the browser.

It looks like the emacs keybinding extension is available for use.
