    By delaying the release of new CPU microcode updates for v1803 and v1809, Microsoft seems to be penalizing users who don't want to immediately upgrade to v1903 when the release version becomes available.

    Or Microsoft could be using Insider Preview rings for their intended purpose?

    If they only delay it a couple weeks, then perhaps it's about testing it out first.

    But it's not being pushed through Windows Update. And if Microsoft is concerned about stability issues, I don't think they would have made it available to v1507 and v1607 Enterprise LTSC users.

    I would probably be less upset if Microsoft wasn't recommending v1803 and v1809 users get the CPU microcode update from their device manufacturers. BIOS updates are always risky.

    I would not be in a hurry to get this microcode update. Yesterday I updated to Version 1903 (18362.113) and everything appeared fine. Today I installed this microcode through the Update Catalog and it disabled Windows Sandbox. Uninstalled the KB44971165 update and all is well again with Sandbox. Don't know if it had affected anything else as I've been putzing with the Sandbox and so noticed that. With the CPU microcode update installed all Sandbox would do is appear to start but not get past showing the small blue screen with the sandbox in the center, like an icon, but would not continue and actually open the Sandbox program.

    I installed the new microcode update on my Linux computer a couple days ago, and I haven't noticed anything unusual.

    I've also disabled Hyper-Threading on both of my Intel machines. On my Windows computer I disabled it in the BIOS, and on my Linux computer I disabled it by configuring the boot loader. I haven't noticed performance degradation on either computer, but I'm not a gamer nor do I run any compute-intensive applications on those computers.

    I got exactly the same on build 18362.113 with KB4497165: splash screen for Windows Sandbox then nothing further.

    Now after yesterday's cumulative update to 18362.116 I get "Windows Sandbox failed to start. (0xc0370106)"

    I submitted a problem report if anyone wants to upvote it: Feedback Hub - Windows Insider
