Microsoft has today re-released the Intel microcode updates for all versions of Windows 10 including the latest April 2018 Update (also known as Redstone 4 or version 1803). The refreshed Intel microcode update apparently adds support for more processors and fixes some bug fixes.
As noted above, Windows 10 April 2018 Update is also getting the refreshed Intel patch. If your PC is on Windows 10 April 2018 Update, you may get KB4100347. But it’s worth noting that the update won’t show on devices that are already patched against the vulnerabilities.
Microsoft’s support page was last updated on September 14. According to recent changes section, Microsoft has added support for additional processors that are listed below:
- Broadwell Server E, EP, EP4S
- Broadwell Server EX
- Skylake Server SP (H0, M0, U0)
- Skylake D (Bakerville)
- Skylake X (Basin Falls)
Not just Windows 10 April 2018 Update, but the older versions of the OS are also receiving new Intel microcode updates. Windows 10 Fall Creators Update will get KB4090007 and KB4091663 is rolling out to Windows 10 Creators Update devices.
If you still use Windows 10 Anniversary Update, you will receive KB4091663 and finally, the original version of Windows 10 will get KB4091664.
Keep in mind that these updates were rolled out to several devices earlier this year and it may not show up on your device today.
The latest Intel Microcode patch is also rolling out via Windows Update and you can get this update from Settings > Update & Security > Windows Update > Check for updates. Your PC has all the necessary updates installed if the Windows Update says the system is up to date.
