Not so black and white...
After reading this and following the links in the article I have been checking my own update.
I use Cisco VPN all day everyday. It was there and working fine post upgrade. I wonder if the missing software after upgrade is due to something like having to reinstall it but it fails for some reason... or I can imagine an older version of the Cisco VPN not being carried over. They are not so compatible with Windows 8 or 10.
Anyway, just saying my CISCO VPN was working fine after the upgrade.
