Electron-builder: Is code signing required for auto-update on Windows?

[mobitar]

I know a lot has changed with auto-update functionality in the last few months, and I've had to learn the hard way that almost every online post about auto-update is outdated (like using Squirrel). In the old directions, code signing was required for auto-update to work properly on Windows. Is this still the case?

Code signing was never required for Windows because on Windows code signing doesn't protect users. Code signing correctly works and correctly protect users only on macOS.

Code signing will be not required for auto-update in the future as well, but we are going to add this check explicitly #1187
