Microsoft released Intel New microcode through windows update KB4558130 for Windows 10 v2004 and windows server v2004 on 01-09-2020

On 01-September 2020, Microsoft released windows update KB4558130 its called intel-microcode update to affected intel processors only for windows 10 v2004 and to windows server v2004.

I would recommend the Intel-based computer users should update the new microcode through windows update.

The reasons to update microcode firmware

• CVE-2019-11091 – Microarchitectural Data Sampling Uncacheable Memory (MDSUM)
• CVE-2018-12126 – Microarchitectural Store Buffer Data Sampling (MSBDS)?
• CVE-2018-12127 – Microarchitectural Load Port Data Sampling (MLPDS)
• CVE-2018-12130 – Microarchitectural Fill Buffer Data Sampling (MFBDS)

Visit Microsoft's official website for detailed information to download the update and to install.

This microcode update only windows os and its temporary, if you reinstall Windows, this update needs to be reinstalled again.

For better security to make your computer intel processor secure, then you need to contact the motherboard or laptop or desktop manufacturer to get newly released BIOS firmware.

Intel inc has already sent all affected processors updated microcodes to all OEM manufacturers.

according to the intel site intel i5 7200u must be patched or update bios firmware with microcode CA, but Asus does not release bios firmware, so i updated .msu file from microsoft site , so this processor microcode updated to CA ( only for temporary
protection)

Intel microcode update for Windows 10 1803

The link you provided is KB4090007 intended for Windows 10 1709, it does not work on Windows 10 1803.

Also, InSpectre displays the same results as the Powershell script, i.e. that Windows 10 1803 does not protect against Spectre.
