How to install Windows 10 October 2018 Update right now

To get the update, you need not lift a mousing finger. Microsoft says the update will arrive automatically via Windows Update. You may not get it right away; as with past updates, the company will gradually roll it out over the next few weeks.

 According to ZDNet, the update will become more broadly available on Oct. 9, affectionately known as Patch Tuesday. 

Microsoft promises to be less disruptive than with past efforts in scheduling the rebooting and installation process.

Back up before upgrading

Before you install any big OS update, it's a good idea to back up your system in case something goes awry during the installation. You can simply upload important files to your preferred cloud service or an external drive. Windows' built-in backup service can be found by going to Settings > Update & Security > Backup.
