With Unidesk, you don’t rely on Windows Update, individual component patch updaters, or have to mess with Linked Clone operations like Reset, Refresh, Recompose, Rebalance. In a Unidesk world, you just perform the update or patch in the appropriate layer, and schedule a reboot of the desktop during the normal maintenance window.
On reboot the Windows 7 desktop is re-composited on the fly with all the new changes, and preserves all user data, user customizations, user installed applications, and so-called “user pollution” where files are stored all over the c:\ drive.
I prefer this approach because it is clean and simple for desktop administrators to manage. Simply schedule updates during the weekly desktop maintenance window or off hours through the Unidesk scheduler.
Make sure that your Unidesk management appliance and cache points all have a consistent and correct system time for the system scheduler to work properly, if you did not do this at installation time.
To do this login to the cache points at https://<cachepoint ip>:8003/ with admin and Unidesk1 ( assuming the default login/password) and at your management appliance at https://<management ip>:8004/ with admin and Unidesk1 (assuming the defaults). Go to Configuration->System Time on the left hand side, then validate that the timezone and current system time are correct.
