If you want to test this, find the date of the update, thenThere seems to be a lot of info saying Windows 10 updates often cause this problem. I tried some of the tips (also mentioned in this thread), didn't work.
go into your admin tools and revert your system to a date,
before the update, that will take you back to the time when
it still worked.
Switch off the automatic updates before you go back, or
before you start using the machine as normal, get a copy of
the update number and always refuse to update that particular
one.
Good luck.
Mike.
