It seems like a busy day for folks at Microsoft. After releasing a fresh new build to Windows Insiders in the Fast ring, Microsoft has also released the ISO images of Build 17758 that was rolled out last week. Slow ring has also received a cumulative update (KB4462120) bringing the build number to 17758.1004. Released last week, you can now download ISO images of Windows 10 October 2018 Update Insider Preview build 17758.

Microsoft is expected to make the Windows 10 October 2018 Update available to the public in… October. However, we are expecting the RTM build to drop very soon. While build 17758 was a likely candidate as it only brought one known issue, today’s build that is currently only available to the Fast ring Insiders brings two new issues along with the regular fixes. That said, Microsoft usually fixes smaller issues with cumulative updates making us hope that we will get the RTM build as soon as this week.
