If for some reason you want ActiveExit to temporarily stop performing its activities, you don't have to uninstall it completely. Instead, you can use its configuration utility (or the Group Policy) to clear the Enable ActiveExit OPTION:

When the Enable ActiveExit option is cleared, no user will be logged off by ActiveExit, even if the idle timeout is up. If a user logs on to the computer while the Enable option is cleared, such a user will not be monitored by ActiveExit.

To resume monitoring user activity and logging off the inactive users, check the Enable ActiveExit box on the ActiveExit configuration window. (Don't forget to also press the Apply or OK buttons!) Note that when you enable ActiveExit, the idle timout starts over. That is, even if a user already was inactive for some time, the inactivity period begins only from the moment when you have enabled ActiveExit.

Another way to temporarily disable ActiveExit is to stop its service, using, for example, the Services management console of Windows. This method, however, is more CPU-intensive: If you stop the ActiveExit service, then not only the user monitoring stops, but also all the monitoring processes used by ActiveExit exit, too. To resume the operation of ActiveExit, start its service, and that would restart the monitoring processes.
