Is the functionality of the trial version limited?

The trial version has the same fucntionality as that of the full version. All functions can be used exactly the same. You do not need a product key to use the trial version.

After the trial period has expired, only TuneUp Rescue Center and TuneUp Update Wizard are fully functional – the other components of TuneUp Utilities can no longer be started.

After obtaining a license, you will receive a product key to activate the trial version allowing full use with no fixed time period.
