You still have not answered what type of updates were being applied that triggered this collapse.
If they were Windows Updates, your smartest move at this point would be to use the rollback option.
I really suspect you have a major hardware failure of some sort that was coincident with, but not caused by, what you were doing. There should be virtually nothing in the world of updates or drivers that would take out internet connectivity (and particularly if it's both WiFi and ethernet wired), USB ports, and an optical drive all at the same time.
You are in a situation where your range of options is extremely limited.
