Windows 10 is the latest version of Windows and there are regular updates and new concept called release build. In each release build, there would be new features and improvements and in case you have been using Windows 10 and upgrading builds regularly, you have noticed several feature improvements in each build and this is the model for Windows 10. Therefore, we won’t see same model as previous version of Windows where we should install Service Packs and upgrade them to new version of Windows (like upgrade from Windows 8 to Windows 10) and instead we only see new builds where we could install them through Windows Update.
Therefore, don’t believe on news about something called Windows 11 and only follow news from trusted and reliable sources. For example, you may follow Windows Blog for the latest information about Windows.
