A new Windows 10 build, the Build 10074 has leaked online and both ESD and ISO files are available now to download. Though you should still do it at your own risk. ESD files are taken directly from actual Microsoft update servers. So this may even be the upcoming new Windows 10 preview build that may come soon to Fast Ring Insiders.
The changes that we have seen with Cortana in the leaked screenshots of Build 10102 are present in Build 10074 too and there are some new icons including icon for WiFi. Check the screenshots above and below.
