I have used System Mechanic for years, across many different computers. Great for a quick tune up on the fly and getting rid of all the junk that builds up on your drives.

Been using it for many years and even have it on my 10 year old computer!

This is by far THE best quick fix I’ve found for fixing issues that nothing nor anyone else seemed to be able to even make a proverbial dent into. Mad props to the iolo crew.

I’ve been using System Mechanic for over 20 years. It is the best I’ve found!

Faster processor

Unparks 100% of processor cores and revs them to maximum clock speed when you begin a system-taxing gaming, programming, graphic design or multimedia task.

Unleashes Internet speed

Greatly improves a whole cache of under-performing Windows Internet settings hidden to most users, for the very smoothest streaming, gaming or browsing available through your network.

Increases drive speed

Stores data to hard disk in contiguous batches, over time preventing hundreds of thousands of file fragments and making the read/write process much faster.
