I see it says that Sea Monkey is my
default Browser?? It should be FireFox.
So by this can you get my USB ports to
function again?

It says you're Licensed, so it seems
to be fine from that point of view.

"How to set Firefox as your default browser on Windows

Click the menu button (three horizontal lines) and select Options.
In the General panel, click Make Default.
The Windows Settings app will open with the Choose default apps screen.
Scroll down and click the entry under Web browser.
Click on Firefox in the dialog that opens with a list of available browsers."

The Windows 7 will likely work slightly differently.

The settings on Windows 10 are protected with a hash,
which is basically a mechanism for preventing Firefox
from directly overriding a Microsoft preference.
That's why in Windows 10, "Choose Default Apps" is
called up, to finish the job.

Whereas in Windows 7, the older ways probably still work,
which may make the procedure a little more direct.
The same initial instructions should apply.
("Menu" button, General, Make Default)

Just a guess on my part.

I don't know what will bring your USB port back.
It would help, if you plugged the USB flash key
into the duff port, and double check it has failed.
Don't forget Safely Remove, when you are finished
the test.
