Well. let's put it this way: your computer is SLOW, it takes HOURS to start, and you're a NOOB (aka someone not that keen on PCs)? This is a free, advanced tool to rejuvenate your computer
nCleaner is an advanced system and application cleaner, (be careful, it has such options like erasing your whole mail/spam folder), a Registry Cleaner, a Tweak Manager, an advanced Startup Manager, a Junk Finder, a Free Space Shredder, a System Resource Monitor, a System Adviser as well as advanced Scheduling.
and it's overall superior to the much more common CCleaner (even if i use them both, since they occupy only a few MB!!)
