Greetings,
I have been a faithful user and a paid customer for some time now.
I also happen to be senior IT professional with considerable experience.
Here are some suggestions on what else CCleaner could clean.
01. Microsoft Windows Event Viewer, Recently Viewed Nodes, (I have been unable to find referencing keys or config files for this)
02. Adobe Reader XI, Recent Locations in Extended Open Menu, (this can be found in Registry)
03. Microsoft Office Visio (2013), Recent Drawings and Recent Folders (like the rest of the Office Suite)
04. Skype, Recent Conversations,
05. Illium Software eWallet, Recently Used Wallets,
06. Lone Wolf Development, Hero Lab, Recent Portfolios,
Kind Regards
Daniel
