Microsoft has released new monthly cumulative updates for all supported operating systems. As usual, such updates do not bring with them any new features, but are aimed at fixing the detected errors and eliminating vulnerabilities. Updates are already available in Windows Update.
Detailed information about the changes in the updates can be found on the official website by clicking on the links below. Nearby you will find links for manually downloading service packs from the Microsoft catalog.
Note. Versions 1903 and 1909, as well as 2004, 20H2, 21H1 and 21H2, share a common base operating system version and have an identical set of system files. That’s why they get the same cumulative updates.
I wish you a successful update!
