I haven't documented these updates since May 2019. Since that time Intel has released patches for several CPUs, but there can be collateral damage, like I discussed it at Windows 10 V1903: Sandbox fails with error 0xc0370106. Microsoft has documented the microcode updates for Windows 10 on this page.
