Along with sending cumulative updates to all the Windows 10 versions available to the public, Microsoft has also released patches for the upcoming Windows 10 May 2019 Update to the Slow and Release Preview rings. As reported earlier, interested users can already get their hands on version 1903, but these cumulative updates will certainly help with performance and stability.
Microsoft was originally expected to deliver this latest Windows 10 feature update last month, but it pushed the public release to May to iron out any last-minute bugs. Hopefully today's quality update will help speed up the process.
Similar to the other updates being released today, May 2019 Update also gets protection against Intel's new speculative execution side-channel vulnerability (dubbed as Microarchitectural Data Sampling or MDS).
Windows 10 May 2019 Update Build 18362.113 (KB4497936) changelog:

Use the registry settings as described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions and Windows Server OS editions).
