Microsoft has officially stopped Windows 11 version 21H2 is no longer supported support for Windows 11 21H2, which she released in October 2021. As of October 10, this version of the operating system no longer receives monthly security updates and bug fixes.
The company recommends upgrading to a more recent version of the OS in order to continue to use the computer safely and access new features.
If Windows 11 21H2 is still installed on your PC, you can upgrade it to 22H2, Moment 3 or 23H2 (this version began to be distributed only at the end of September, so it is not available to everyone yet). The latter two contain many new features and improvements, including support for the Copilot AI assistant.
Microsoft is also planning to introduce Moment 4 in November.
