After months of testing, Microsoft has released Windows 10 May 2021 Update (21H1). For those who do not know, Windows 10 May 2021 Update is a feature update, although it hardly includes any new features.
While Windows 10 May 2021 Update is rolling out, it will not be automatically installed on your computer. You need to manually check for this update and then install the same.
