ccleaner log, is it safe to delete?

I had ccleaner for a short period of time, and i always analyze then run the cleaner, but on the left where i said windows if i scroll down it had advanced,
-old prefetch data
-menu order cache
-tray modifications cache
-windows size/location cache
-user assist history
-llS log files
-hotfix uninstallers
-custom files and folders
i never checked the advance but today i did check advance and all of them and just clicked analyze, this is the log file(somewhere on this post, lol)just wondering if i could run the cleaner and clean these things, is it safe?

thanks chris:major

 

I love CCleaner and use it daily with no issues but keep to the default settings.

The files you list are in the Advanced Area, unless you're an advanced user, I would leave them alone. By default those files are not checked (advanced features are turned off), some info in logs might be needed later also can remove saved passwords, hotfix info.
