How to delay Windows 10 version 2004 and prevent it from installing
A number of users are interested in delaying the upgrade to Windows 10 version 2004, also known as "20H1" and Windows 10 May 2020 Update. There are many reasons for this. Most users don't want to disturb their existing setup and do not want their custom settings getting reset again by the version 2004. Others would like to avoid compatibility issues. Here is the official way to postpone the upgrade to Windows 10 version 2004.
When a new feature update becomes available, it often gives issues due to unknown bugs, driver issues, or internal updates in the OS. It is not possible to test all existing device configurations, so these are reasons for plenty of users to delay the update.

However, it is already possible to download the OS with Media Creation Tool, or get ISO images directly.
