Microsoft has released documentation for the features that have been deprecated in Windows 11 version 23H2. While they often provide information about removed features as well, the page for removed features has not been updated yet.
According to Microsoft Learn’s page on deprecated features for Windows client, each version of Windows adds new features and functionality. Occasionally, new versions also remove features and functionality, usually because newer options have been added.
Deprecated features are those that Microsoft is no longer updating and are planned to be removed in future versions of Windows. I was curious to see if the Windows Maps and Movies & TV app would be on this list, given the recent news, but they are not. Instead, only three low-level features have been deprecated.
The deprecated features are as follows:
1. Computer Browser: This outdated service and its associated driver have been included in Windows versions for backward compatibility since Windows NT. They were disabled by default in Windows 10 when support for the SMB1 protocol was removed, and the same action was taken for Windows 11.
2. Webclient (WebDAV) Service: WebDAV was a set of extensions to the HTTP protocol used for mounting folders on remote Windows PCs and servers as mapped network drives. It dates back to Windows Vista, is no longer started by default, and has been replaced by more modern methods of file sharing between PCs on a network.
3. Remote Mailslots: This protocol, introduced in MS-DOS, is described by Microsoft as dated, simple, unreliable, and insecure IPC (interprocess communications). It was first disabled by default in Windows 11 Insider Preview Build 25314 (part of the Canary channel) in March. However, there is conflicting information about whether it first appeared in Windows NT.
Overall, there aren’t many significant changes in terms of deprecated features.
