Windows 10: there is KB4577063 for the May 2020 Update

Windows 10 cumulative update KB4577063
Brings the platform to build 19041.546 and includes a long list of bugfix. Some of those contained in the full-bodied changelog concern a problem found in the Internet Explorer mode of the new Edge browser, a bug that prevented the language bar from being displayed correctly and another that resulted in non-facial recognition via Hello using certain webcams. Also reduced distortions generated when playing content in Mixed Reality viewers such as HoloLens.The download and installation process of the update can be started simply by opening Windows Update on computers and devices with Windows 10 that already have the May 2020 Update.
At the gates there is also 20H2, as already written on several occasions, more a service pack than a real full-bodied update. It will make its debut in about a month. Then, starting in 2021, Microsoft could choose to review its roadmap by distributing only one major update per year as assumed in early September.
