Microsoft released KB4524147 to fix the printer issues that were introduced with KB4522016. Too bad they broke more stuff! According to BetaNews, people are reporting broken Start Menus with this update.
For me, it didn’t break the Start Menu but like the previous update, the Action Center was broken. This means I can’t dismiss notifications and I can’t reconnect to Bluetooth headphones using Windows Key+K since that part uses the same overlay that the Action Center uses.
