Great contribution Alan!
I use CCleaner at work, and I need to clean multiple computers. These are in public use so there should not be anything of value in the temp folders.
That's why I use INI files, so that the settings are specific to the computer, not the user.
And if it's been checked to run CCleaner on startup, it makes an entry in HKEY_LOCAL_USER which means it only runs on the specific user. Any other user on the same PC must also tick this choice, and also to make any changes to what CCleaner will clean, since the settings are user-specific this way.
Either open your daughters account and make the changes or you can switch to a global choice (INI + LOCAL_MACHINE).
Edit: Added: Isn't it common practice to place (on local machine, not on network) all your work in the user's profile folder? And temp folders are only to be used by applications, temporarily, to store information (often can be sensitive which _should_ be remove)?
Please enlighten me as to what files of importance could be in the temporary folders? Thanks.
