On Windows 10, you and I've been able to copy and paste text and images for a long time, but it's been a limited experience that only supported copying one piece of content at a time and no interface to view the item temporarily stored in the cliboard.
To overcome these limitations and to make the experience more useful, back with the release of the October 2018 Update, Windows 10 introduced a secondary feature for known as "Clipboard history" that tracks the text and images (up to 4MB) that you copy and adds an interface to view the history of copied items. The feature even includes an option to pin items you copy more frequently to paste them more quickly.
