Although it’s recommended to install Windows 10 version 1809 (October 2018 Update) using Windows Update, Microsoft also supports upgrades using its Media Creation Tool.
You can download the Media Creation Tool from this Microsoft support website to download the October 2018 Update files to perform a clean installation, in-place upgrade, or to create an ISO file as soon as it becomes available during the first or second week of October.
Also, you can use the Media Creation Tool to create a USB bootable media, which you can sue to start your device to upgrade to the latest version of Windows 10.
If the tool doesn’t work, then you should try the Update Assistant (when available), which is a tool similar to the Media Creation Tool, but it only allows you to perform an in-place upgrade. (Microsoft designed this tool to get around Windows Update when it’s not working.)
Microsoft is expected to begin the rollout of the refresh some time during the first or second week of October, but it’ll be a gradual release, and it could take weeks until every device receives the update. Microsoft will start upgrading devices with newer hardware first, and then, when version 1809 has proven to be stable, the rollout will continue to other computers.
The Windows 10 October 2018 Update isn’t as significant as the April 2018 Update, but you’ll find a number of new improvements and several new features.
- Windows 10 version 1809 (October 2018 Update): 7 Best new features
- Windows 10 version 1809 (October 2018 Update): 10 Best hidden features
If you need to download the Windows 10 October 2018 Update ISO file directly, you can skip the Media Creation Tool using this workaround.
