ccleaner, buy or free?

I dont need to buy this, i have one computer and I just use WORDS, gmail, kingdom rush,chess on it
There are other versions of CCcleaner, IE slim, etc, I dont need those, right?

 

Where are you seeing you have to pay for CCleaner? All versions are free for home use, the slim version has no toolbar that they use for revenue and they have shareware business editions. If you have no desire to remove useless junk files from your system, then no, you don't need it.

 

You can see the differences between the free and paid versions here http://www.piriform.com/ccleaner/download - the functionality is the same for all, except for the network edition.

There are different ways to install; see http://www.piriform.com/ccleaner/builds

 

im using free!...
and that is all i need.

 

Free is the best one.

No real point in Paying 50$ for one or two extra items that might not work for you.

 

But you are always welcome to donate something at the Piriform (CCleaner) website.
