Microsoft has released the ISO files for Windows 10 Insider build 15042 to the public. If you're an Insider looking to do a manual fresh install of build 15042, the ISO files will let you do just that.
This build originally rolled out to the Windows Insider Fast ring late last week with a smattering of tweaks and fixes. The Fast ring has since moved on to build 15046, which similarly adds a bit of spit and polish as development on the Creators Update starts to wind down.
If you want to get started with build 15042, you can grab the ISO files now directly from Microsoft's Windows Insider website. The instructions for creating the an install disk with the files are found there as well.
