Microsoft begins autoupdating more devices to Windows 10 21H1

Microsoft has announced that they have started auto-upgrading a larger number of Windows 10 devices nearing end of life to Windows 10 21H1.

Earlier this month, Microsoft began training their machine learning algorithms by automatically upgrading a small amount of Windows 10 2004 users to Windows 10 21H1.

Microsoft did this training to discover issues that may arise during the update process before upgrading a larger population of Windows 10 users.

For most people, Windows 10 21H1 is still being offered as an optional update displayed when manually performing a 'Check for updates' in Windows Update.

Today, Microsoft announced that they are now automatically updating a larger amount of Windows 10 devices that are reached the end of servicing to Windows 10 21H1.

"We are now starting a new phase in our rollout. Using the machine learning training we have done so far, we are increasing the number of devices selected to update automatically to Windows 10, version 21H1 that are approaching end of servicing," explains Microsoft on the Windows 10, version 21H1, notifications page.

"We will continue to train our machine learning through all phases to deliver a smooth update experience."

With Windows 10 2004 reaching its end of life on December 14th, 2021, more devices running this version of Windows 10 will automatically be upgraded to the latest version.

For those who do not wish to upgrade to Windows 10 21H1, you can defer the feature update using the 'Select when Preview Builds and Feature Updates are received' group policy found under Computer Configuration > Administrative Templates > Windows Components > Windows Update > Windows Update for Business.
