Sadly, my workaround is only effective per update file meaning, the update stops after the current fspackage.xxx finishes downloading. You then have to clear the right-click menu to continue. I suppose this behavior could still be useful with an AutoHotkey script.
Additionally, to those who have persistently claimed that CPU/GPU were being utilized to decompress the files, that’s clearly not the case since all the files are being processed after they’ve all finished downloading; a further insult to injury.
