The Recycle Bin shortcuts have been reintroduced in the latest update, v7.6.
If you update your CCleaner7 to v7.6 then they should be back.
The only way to get v6 functionallity back is to reinstall the final v6 version, v6.39.
However that version is now 8 months old and will never be updated, parts of it have already stopped working properly and it will fall further behind as browsers and apps change over time.
If you do want to go back to v6.39 then see: How to Roll Back from v7 to v6.39
Follow ALL of the instructions there, particularly about turning off the Automatic Updating and deleting ‘CCupdate.exe’, if you do not follow the instructions then your newly rolled back CCleaner will just update to CCleaner7 again.
