Last week, Microsoft released Windows 10 Insider Preview build 17744 to the Slow ring. Today, the company is releasing ISO images for that build, just in case you want to do a clean installation of the OS.
Just as it did with build 17738, the ISOs were released in a timely fashion, something that's been rare for the Redstone 5 development branch of Windows 10. But as we get closer to the RTM build, Slow ring builds are more frequent, and so are new ISOs. This is the third set of ISOs to be made available for Redstone 5.
Once Redstone 5 hits the general public, it will be called the Windows 10 October 2018 Update, or version 1809. That means that it will be out in - you guessed it - October 2018. That also means that Insiders should have a finalized build sometime this month. After the Fast ring gets it, it should be promoted to the Slow ring and then Release Preview.
If you want to download the ISO files for Windows 10, Windows 10 Enterprise, or Windows 10 Home China, you can find the files here.
