One exception is the HeiDoc.net Windows ISO Downloader tool, which lets you get the official Windows 10 ISO download from Microsoft.The program doesn't come from Microsoft but it does grab the ISO directly from Microsoft's website (software-download.microsoft.com), so unlike a torrent site, it's most likely safe and can be a good alternative if Microsoft's tool (above) didn't work for you.
