How to Get the Windows 10 October 2018 Update ISOs Already Today

Windows 10 Build 17763.1 is believed to be the RTM for the October 2018 Update. Here we look at how to download this build before it is officially launched next week.


has been testing Build 17763.1 in preview on the Insider Program in recent weeks. ESM files for this build are expected to be the release to manufacturing (RTM) of the October 2018 Update (version 1809). As that name suggests, Build 17763.1 will not be launched fully until October, specifically October 2.

Luckily, there are ways you can get Windows 10 Build 17763.1 before Microsoft rolls it out next week. Below we will detail a method for updating the ISOs right now, but first some important caveats.

Not least the possibility Build 17763.1 is not the RTM release. While the consensus seems to be this is the finalized version of the October 2018 Update. However, there are instances where the supposed RTM build has been succeeded by a new release.

This was most evident with the Windows 10 April 2018 Update. Microsoft sent out an RTM build for the update in the form of Build 17134 but later found a bug in the release. The company was forced to continue tweaking the April 2018 Update with a couple more preview builds. Because of this, the April 2018 Update was delayed nearly a month.

While this could happen again, it is worth remembering the situation surrounding the April 2018 Update was rare. Considering we already know the October 2018 Update will launch in early October, it seems very likely that Windows 10 Build 17763.1 is the RTM.
