I have encountered two problems since the update, one on PC and one on laptop.
I run Acronis True Image 2019 on my desktop and since the update just after booting up I get a pop up warning that Acronis Scheduler Service is not running, also found out that the Active Protection within Acronis was not starting automatically either.
On the laptop after booting up I get an on screen warning that 'The system needs to be restarted for Control Center Application'. Simply closing this box appears to allow the laptop to function normally.
