Group membership update without reboot

Hi,

 If I change the group membership of a Windows 10 or 2008 or 2016 computer will the group membership change without a reboot? Is group membership updated without a reboot, say after a timeout period? 

The only other method I'm aware of is a manual refresh using the klist purge switch. 

I'm evaluating when a scoped GPO will apply.

Thanks
