Good Day The,
My name is Carlo, I am also using Windows 10 pc and community member like you. Let us work together to sort this out.
That was the name of your computer that was set, you can actually change it in the settings.
-Press Windows key + X
-Go to Settings
-Click System
-Look for "About"
-Under Device Specification you will see Rename this PC
-Set your preferred name to appear.
Restart and check the device manager, if it will show the name you set.
Have a wonderful day ahead and stay safe.
Sincerely,
Carlo T.
