Impossible to update the OS. S/N 5CD02612DM

I don't succeed to update the OS from Windows 11 22H2 to the current version or anyway newer.

The HP assistant seems not to recognize the OS currently installed since it declares it is Windows 10, on the contrary it is Windows 11.  The Windows Update application states: "La tua versione di Windows ha raggiunto la fine del servizio."

The only suggestion I can offer would be to try the in-place upgrade from W11 22H2 to W11 25H2 by clicking on the W11 installation Assistant button (1st option at the link below):

Download Windows 11

If that doesn't work, you will probably have to back up any files you don't want to lose and clean install the latest version of W11 using the Media creation tool (2nd option) on the above link.
