Hi,
Are you on build 25h2 or 24h2?
Go to Start > Settings > System > About and tell me which Windows 11 build you are on.
Or
Are you trying to upgrade from Windows 11 Home to Pro?
Follow the procedure below:
Open the command prompt (admin) and run the commands: sfc /scannow and dism /online /cleanup-image /restorehealth, wait for the process to finish and restart the computer.
Then perform a clean boot and uninstall applications that you do not use if you want.
Thanks
