When using a Windows Internet browser, pressing _____ reloads a page.

Pressing F5 is a commonly recognized method for reloading or refreshing a webpage in Windows Internet browsers. This key is specifically designed as a shortcut for this action, making it a quick and efficient way to refresh the content displayed on the screen. When a user presses F5, the browser retrieves the latest version of the page from the server or refreshes the content from the cache, ensuring that they see the most up-to-date information.

Other options may not be standard shortcuts for reloading pages in most browsers, which is why they are not as widely recognized or utilized. For instance, while Ctrl + R can also be a valid method to refresh a page in certain browsers, it is less universal than F5. The other options like Alt + Refresh and Shift + Reload could refer to unique functionalities or might not be recognized in many common browser settings, reinforcing F5 as the best answer for this question.
