Earlier today, Microsoft announced its rollout plans for the Windows 10 May 2019 Update, which will arrive in the Release Preview ring next week. In preparation for that, the company is releasing KB4497464 to both the Fast and the Slow rings, bringing the build number to 18362.30.
It's worth noting that if you're on the Slow ring, you'll need to install KB4496796 (build 18356.21) before this is offered to you. You might recall that there was a bug that prevented build 18362 from being installed on top of build 18356, and that was fixed yesterday with build 18356.21.
There are a few fixes in this update that Microsoft noted:
We fixed an issue where AAD users were not able to sign-in after updating to 19H1 on AAD-joined PC not enrolled into MDM.
We fixed an issue where users were unable to enable\disable .NET Framework or other optional feature- on-demand (FODs) after installing recent Cumulative Updates.
We fixed an issue where a user’s PC may get into a unbootable state after installing a Cumulative Update and then installing a optional feature-on-demand (FOD).
After this, the Release Preview ring is the next stop. Following a solid month of testing, the Windows 10 May 2019 Update is slated to be released in late May.
