Not getting windows 11 update in windows update section

It's being rolled out gradually - -and it may take until well into Summer if not Fall 2022 for all eligible systems to receive the update.

Given all the issues that have surfaced with Windows 11, unless you absolutely need it now (in which case you CAN manually download and install it), you have a lot to gain by waiting and letting others find all the bugs, deficiencies and incompatibilities in the new OS.

@ejn63 is spot on with the rollout. But your post seems to imply that you had Windows 11 installed already. If so you probably will not see the update offered again. However you can go to this  page and either click on the Installation Assistant which is the update version. Or you can click on the media creation tool and update or clean install from the installation flash drive that is created.

Had you received notification to upgrade to W11 before???

If so you may need to do a fresh install instead of an "Upgrade"

I installed it via installation assistance last time but I did not roll back using windows feature. I reset it with a factory image. Will I receive notification in that case or I will have to install using installation assistance
