Issue: How to Fix “Service Registration Is Missing or Corrupt” Error on Windows 10?

So, I downloaded and ran the Windows Update Troubleshooter, which reported an error “Windows Update: Service Registration Is Missing or Corrupt.” The troubleshooter did not fix it, so I guess I should do something to fix it. Could you please help?
