The "slim" build of CCleaner according to Major Geeks? in CCleaner Posted August 27, 2014 I am no more informed on that then you are, I can just ban spam, other than that I'm just a normal piriform user like or unlike yourself Edit: that said, the slim is redundant imho. The portable can be unzipped on top of existing installs, and can be coverted to non-portable easily. As well, there's a pro version which allows piriform to pay bills but not enough to warrant a free un-hobbled awesome set of programs without some sort of payment-based system. google pays the bills...do you? Some reading this elsewhere are getting a mixed signal if the Slim version is soon to be pulled from the CCleaner family of software. This probably should be clarified as many run the free Slim version without having to jump through hoops to get the build. If you're asking if costs like web hosting and staff are motive or justification to pull CCleaner Slim out of the line-up, that's something you folks have to arrive at and make a statement.
