After a fresh installation of W11 Pro and the installation of MS Office 2019, CCleaner using the defaults for Custom clean clears out the "pinned" document settings under Word and Excel.
Additionally, the same Custom clean process causes my HP 6055 printer to be in an error state. I then have to use the HP Print and Scan Doctor to repair the issue. The printer is marked as the default and it shows under USB Devices in Device Manager.
