While Bandicam's free trial version is a great way to test the software, it comes with some significant limitations. The free trial version will only allow you to record video for a maximum of 10 minutes, and it will also display a watermark on the recorded video. Additionally, you will receive constant reminders to register the software, which can be frustrating and distracting.
Built directly into Windows (Win + G), it allows for simple, free recording of games and apps without any extra downloads.
