Recommended Posts

Could someone please advise whether CCleaner is free for commercial use i.e. can I use it on multiple machines in an office environment ?

I can't find any license details on any Piriform sites regarding it other than the copyright notice at the bottom of each page.


It's freeware, and doesn't have anything explicitly written that it can't be used commercially.
