Microsoft’s Windows Insider team pulled double duty yesterday. In addition to releasing Windows 11 Build 25151 to the Dev Channel, the company shipped Windows 11 Build 22621.169 to Release Preview Insiders. Like its Dev-channel cousin, the new Release Preview build is fairly minor.

Build 22621.169 includes just two new items: a Server Message Block redirector and support for Transport Layer Security 1.3 in Windows client and server Lightweight Directory Access Protocol implementations. Needless to say, these are not consumer-facing features, but they’re important nonetheless.

Here are all of the improvements from Windows 11 Build 22621.169, asoutlined by Microsoft:

The build is available for Release Preview Channel Insiders on Windows 11 version 22H2 or later.
