I ran a diagnostic test from my HP desktop, on Windows Updates and other functions. HP Help has several tests to use on Windows 10. The test took several minutes, and wasn't completed, when I canceled it. It seems to have wiped out Updates. Nothing appears except the word "Updates," when I go there. I only get one chance at Updates, and am unable to access it except initially from Settings. For instance, if I got to Security, then try to go back to Updates, nothing happens. Any suggestions?
