Inspiron 13-7378 Windows 11 upgrade?

Hi

Try Rufus, as it does offer some options that may be beneficial is my thinking.

You'll need to bypass the CPU check, since the system does not meet Windows 11 requirements.  There are ways to do that, but realize that all future updates then have to be done manually (Windows update won't work for the major updates any further).

Flyby11 is one utility you can use to force the update.
