The upgrade has had some fun with my machine.
a) Restart after updating - well, no, it powered the machine off
b) ICMP (inbound) ping/response was disabled, after I'd explicitly enabled it
c) Jumbo Frame support magically got disabled
d) System Restore - also magically turned off - I created a Restore Point FIRST, and when I ran some diags/checks afterwards, System Restore on C: was disabled.
I'd advise you to check all your settings, just in case...
