Hi, latest microcodes updated for Gigabyte GA-Z97X-Gaming 7 vF8 (Feb 2019 for Haswell, June 2019 for Broadwell) should include MDS mitigations and this family (4th/5th gen) is not subjected to Plundervolt so do not expect newer microcodes until Windows Insider 20H2 releases them.
Most Windows 10 right now are running microcode 0x25 for Haswell.
