Microsoft formally announced today that the April 2018 Update will begin rolling out to the public on April 30. But ahead of its release, Windows Insiders are getting another small update of their own.
Insiders on the Fast, Slow, and Release Preview rings that are currently on build 17134.1 will now be able to download KB4135051, which ticks the build number up to 17134.5.
There's now word on exactly what's new in 17134.5, but it likely includes some smaller changes to get things ready for the public rollout on April 30.
If you're an Insider, you should be able to grab 17134.5 now via Windows Update. And as we wait for the public release to begin, be sure to check out our full, in-depth review of the April 2018 Update for more.
