Microsoft has finally started to release Windows 10 May 2019 Update today after months of testing. You can head over here to download ISO files (32-bit and 64-bit) or to this guide for the manual installation process. Along with the fancy new feature update that finally introduces the ability to delay updates, Microsoft is also releasing a cumulative update to Windows 10 October 2018 Update (version 1809) and April 2018 Update (version 1803).
