Well, I went into the settings for CCleaner Custom Clean to do as you suggested and discovered the boxes you suggested unchecking were already unchecked, so I'm not sure what to do now. The only boxes that are checked are:
MICROSOFT EDGE: Internet Cache, Internet History, Cookies, Download History, Last Download Location and Recently Typed URLs
EDGE CHROMIUM: Internet Cache, Cookies, Internet History, Download History, Last Download Location, Metrics Temp Files, Bookmarks Backup
INTERNET EXPLORER: Temporary Internet Files, History, Cookies, Recently Typed URLs, Index.dat files, Las Download Location
WINDOWS EXPLORER: Run (In Start Menu)
SYSTEM: Empty Recycle Bin, Temporary Files, Clipboard, Memory Dumps, Chkdsk File Fragments, Windows Log Files, Windows Web Cache
