Over the weekend, Microsoft took to the stage at IFA 2018 in Berlin to announce the name of the next major update to Windows 10. What was earlier codenamed Redstone 5 is now officially the Windows 10 October 2018 Update and will arrive some time in – you guessed it – October.

This will technically be Windows 10 version 1809, with the more friendly 'October 2018 Update' nomenclature keeping to Microsoft’s usual naming convention – the previous refresh was called the Windows 10 April 2018 Update.
