For years now I've been backing up my iPhone to my iCloud account since my laptop stopped backing up my phone for some odd reason. I don't know what caused this or how to fix it, but at this point my iCloud won't back up either because I have used up more than the allowed space. So now I need to figure out how to force a backup on my pc eventhough iTunes doesn't allow me to do so and shows my last backup as UNKNOWN. I've searched online and can only find a fix for Mac.

Also, I cannot change the name of my phone...it's still listed as what I had my 4 named as
