This is equivalent to pushing the “Clear All” button in the Clipboard history window, but it also works with Clipboard history turned off. Click on the “Clear” button, and the clipboard will be erased. Navigate to Settings > System > Clipboard and locate the “Clear Clipboard Data” section.
You can also clear your clipboard data in Windows Settings. If you would like to prevent Windows from storing your Clipboard history, you will need to disable the feature in Windows Settings. Note that with Clipboard history enabled, new items will continue to appear in the Clipboard history list every time you copy something to the Clipboard. Click the small pushpin icon beside the remaining items on the list and click “Clear All” again.
If any items remain on the list after you click “Clear All,” then they are likely pinned in place. To remove the entire contents of the Clipboard history list, click “Clear All” in the upper-right corner of the Clipboard history window.
