The Windows 10 May 2021 Update has a short list of removed features.
Most notably, the legacy version of Microsoft Edge is no longer supported.
The update also has a couple of features that are no longer in development.
Windows 10 updates generally bring new features to PCs, but Microsoft also occasionally removes features through major updates. These features are sometimes replaced by other options, but in some cases, Microsoft simply decides to go in another direction. The Windows 10 May 2021 Update is no exception, as it includes a short list of removed features.
In addition to removing a couple of features, Microsoft also stopped developing two features. These deprecated features are still available but aren't actively developed. They may be removed in future updates but are available for now.
