The major update of Windows11 this year to 24H2 is released early this month. You can update now, or some of us want to wait until bugs are worked out, that is fine too.
To update, you might have received a notice from Microsoft and just follow the link.
If you don't want to wait and want it sooner, there are ways too.
Go to settings, windows update and click the link on upper right and check for update. If the update is ready for you, just follow the link and get it updated.
If that did not work, go to this site: https://www.microsoft.com/en-au/software-download/windows11
Check the first "download now" button under Windows 11 Installation Assistance. Just follow the instructions. You will be given the choice of keeping you personal files and apps or install new. I wanted to keep my files butI was not given the choice to keep the file. I aborted the update and tried that again afterwards. The second time did go through without any issue.
