There are a few tools you can use to download Windows ISOs from Microsoft without visiting a Microsoft site itself -- sometimes it's quicker/easier since there's no sign in, and you can easily access versions that aren't offered to everyone. It looks like Microsoft put a hard stop to this, so if whatever tool no longer works, don't go nuts trying to figure out what went wrong... hopefully someone(s) will come up with a way to make this sort of thing work again, but it may not be possible.
