[German]Another small addition: Microsoft has already released various Intel Microcode Updates for Windows 10 Version 1507, 1607, 1703, 1709, 1803 and 1809 in an updated version on 26 June 2019.
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.
