Windows 11 failed to install

It is difficult to not let my ire loose here. I have many hours now trying to upgrade from W10 to W11, and am thoroughly frustrated.

Several months ago I installed W11 straight from the Updates page, so easy. I didn't like it and reverted. Now with the coming end of support for W10 I decided I am going to have to go with W11 like it or not. Only now I cannot install from Updates in my Windows 10 settings--it doesn't provide any way to do so. Looking online I have tried every possible solution I can find, nothing works. I don't feel I should be asked what steps did I try, I feel this is an issue that many people are experiencing, and Microsoft is open to criticism for not resolving the issue.

A solution that works the first time would be appreciated.
