Intel’s January 2021 microcode update will mitigate the latest security vulnerabilities. It is hoped that this update will not cause unnecessary performance side effects caused by the company's previous large security version. Microsoft also seems to be keeping its promise of using Windows registry entries to block Windows 10 patches. This means that if you block Windows updates using the registry editor, the patch will not appear.In addition to the 20H2 version and 2004 version, another patch is being rolled out to desktops of 1909, 1903 and older. Those using older CPUs and Windows 10 versions will have to wait longer to receive these security updates, and there is currently no news on when they will arrive.
