Hello,
Looks like you're an older version of Windows 11 hence not getting regular updates.
You can try manual upgrade to latest version i.e. Windows 11 26H2 using ISO file.
Follow these steps:
Download Windows 11 26H2 ISO from the official Microsoft website.
Double click on it to mount it to a DVD drive.
Then go to DVD drive, double click on setup.exe to proceed.
Follow on-screen instructions to complete upgrade.
Hope this helps!
