Microsoft is working on a fix for KB5001030 install fail in Windows 10 build 21364 Apr 22, 2021 06:06 EDT with 0 comments Yesterday, Microsoft released Windows 10 build 21364 to Windows Insiders in the dev channel, the build brought quite a few new features such as support for Linux GUI apps, an Eco mode in Task Manager, as well as Task Manager improvements for Microsoft Edge, and more. However, as is common with preview builds, there were also a few known issues to consider. One such issue was added to the Windows Insider Blog post announcement after the build was released stating that some Insiders were reporting error 0x80092004 when installing KB5001030 – 2021-02 Cumulative Update Preview for .NET Framework 3.5 and 4.8 after updating to the build. As such, it doesn't affect everyone. In our own testing, the Cumulative Update installed before build 21364 did and we have not run into any problems.
