Windows 10 version 2004 is also known as the May 2020 Update. Although the May 2020 Update is available, that does not mean that all devices including Microsoft Surface will be able to download it. This is because some devices do not have suitable drivers for the May 2020 Update.
Earlier this week, Microsoft began launching the Windows 10 May 2020 Update for all Windows 10 users worldwide. This major feature update comes with a number of new features and updates that will enhance the user experience.
