I had pulled a W7 out of storage at the office and same thing. I played with it a little and found IE to be less than IE 11 so I manually downloaded it from Microsoft, installed it and it began to update.
Remember I can't know if you have an antivirus suite known to interfere with WU (windows update.) I'm a little tired of Norton, McAfee and Kapersky on that subject. So much so I call the behavior thuggish.
I can not find any updates for my Toshiba Laptop.. It keeps checking for updates without finding any..
