Sage implemented an automatic license key update program starting with Sage 100c v 2016 PU 2.
Versions of Sage 100 and Sage 100c which auto-update keys:
2015.5+
2016.2+
2017.0+
Note: Versions 5.20.3 (2015.3), 5.20.4 (2015.4), 5.30.1 (2016.1) will have the ability to update the payroll expiration date with the Update button by installing the Hot Fixes based on version KB 83158 (

I haven't seen UI changes (ie Custom Office) though if a user was presented with Classic/Standard choice and chose Standard they would notice that the shortcut ""buttons"" were gone and not transferred to the new Standard UI (themes/colors don't transfer). I can't say whether grid changes were also cleared although my first suspicion would be that the user tried to reset the panel in order to get back to the old UI which would also reset any grid level changes.
I have seen updated keys push sooner than 28 days in the case when the customer made a change with Sage -- usually removing user licenses.
Early on there was some discussion about whether this update could somehow be blocked by disabling the ability to access the licensing server. I don't think this is (easily) possible and seem to recall that doing so resulted in some type of other error messages. It seems 100c needs an Internet connection as evidenced by this Sage KB - Could not contact the license and subscription service in the allowed time. If the problem continues, please contact Sage Support.-

It would be helpful if Sage 100c allowed for an administrator to push out a standard UI setup to end users. Many of the remaining Sage 100/100c customers are 10+ user distribution sites. In many cases, an administrator would like the order entry and other users to have a standardized desktop. It's somewhat 1980's technology to have to go workstation to workstation at a 40 user site (1/2 of who/whom aren't in the office or are remote) and coach users on how to slightly modify the new UI.
An ability to centrally maintain all user desktops is a feature many of my 10+ user sites would appreciate.
