Whatever you choose to do, create a backup (image) of your current system first
Macrium Reflect (freeware from MajorGeeks, other links to direct Macrium dowenloads elsewhere in this forum. The free version is no longer available from the Macrium website)
and/or
AOMEI Backupper (freeware)
Create image(s), create a boot USB drive from either/both programs respectively (and even a spare copy as insurance)
Then run the update directly from the MS site. Don't use any links clickable in that message window shown in your OP, just in case it's not genuine MS
EDIT : And if you've a mind to, and you don't already do it, make an extra backup of your personal data in native format (i.e. ,doc as .doc, .jpg as .jpg, etc) using something like SyncbackFree
EDIT 2 : Rollback withing 30 days is still avaiable, AFAIK. However, for me, that would leave a pretty messy system ... upgrade <> downgrade. Alternate absolute ideal way would be ...
- swap out your existing drive for a blank SSD. That would leave your current system, warts and all, intact in case anything goes pear shaped (as they used to say in The Bill) with the new system, and/or it's not to your pleasure
- clean install of Win 11. Test/play with to your hearts content.
In this guide, you’ll learn the steps to use DISM commands to set the number of days after an upgrade that you can uninstall the upgrade before the system deletes the previous version.
This happened to my Win11 incompatible laptop as well! As soon as I clicked Stay on Windows 10 for now, the update window reverted back to the usual red X "This computer cannot run Windows 11..." message.
It seems to be a new bug as other users are reporting the same on various sites. However as others have said if you try updating it will fail.
I saw an article yesterday and it was an error by MS.
It will not install W11.
