windows 11

On several occasions, Windows Update has said that my laptop, Inspiron 15 5000 is suitable for upgrading to Windows 11.

Two days ago, I performed this and a day later had another major uplift from 23H2 to 24H2.

It went very well and is working well. Until I log into DELL support which tells me:

"The Microsoft requirements for Windows 11 are not supported on this device. Read more about system requirements here."

So who am I supposed to believe, and what's next for me? As my machine is well outside warranty, I am not in a position to engage with DELL.

Any ideas?

My machine is:
