What are key differences between a private web browser window and a regular web browser window?

A private web browser window offers a distinct set of features compared to a regular window, particularly regarding user privacy and data management. The correct answer points out that private windows do not store cookies persistently. This means that when you browse in a private window, any cookies collected during that session are not retained after you close the window. This feature is designed to enhance privacy, ensuring that your browsing information isn't stored on your system for future sessions, which can be particularly useful when using shared or public computers.

This characteristic is crucial for users looking to keep their browsing activities discreet, as cookies can track user activity across different sessions. In contrast, a standard web browsing window typically allows cookies to be stored, which may lead to personalized content and persistent login sessions but at the cost of greater exposure to tracking.
