You can restrict PC usage with Easyuac.
With Easyuac, you can restrict the use of a PC. You can set these restrictions based on hours and apply blocking measures. The user cannot use or access the PC during the restricted hours.
Because all data recorded by Easyuac, such as screenshots and activity logs, is stored in the cloud, access is possible even when the PCs are turned off, and monitoring and reporting can be obtained.
