The simplest fix when clipboard functionality is not working is to open Task Manager (Ctrl + Shift + Esc) and select Windows Explorer from the Processes tab, then click "Restart". Be sure there are no file copy processes ongoing, and any open Windows Explorer windows will close, but it should restore your clipboard functions.
Check the Clipboard history option in Settings ->System ->Clipboard, make sure it is enabled.
