Thanks Round2It for helping! As Round2It explained, a Managed User installation allows user settings to be saved in a central location (eg a shared folder on a server) and using the Teacher's Toolkit, these settings can changed or Activity Logs can be viewed. An Unmanaged User setup does not use the Toolkit or save User Settings to a folder. They are just saved in the student's Window's profile. The_Oracle, if you need any further assistance, please email us at support @ texthelp.com and we can advise you further.
Regarding the prediction issue that Round2It described, if you restart the PC after installation you shouldn't have to edit the registry. Let me know if you have any issues.
