Microsoft is rolling out Windows 11 sequentially - you can either wait until it appears in windows update, or you can manually upgrade or install it yourself.   Some systems will not see it in Windows update until late 2022. To manually install now, make and test a full system backup first, and then see [URL]  
Is the Windows 11 upgrade available for my Inspiron 3583 laptop? I have run the PC Health Check and all the tick marks are marked. I have done everything I could think of but WIndows Update still says Get Ready for Windows 11. I hope I didn't miss out on getting this free upgrade.
