PC Magazine – Editors’ Choice

“System Mechanic’s evolution from tune-up utility to an all-around PC enhancer is one that you shouldn’t overlook. Plus, you get unlimited licenses, which can go a long way to justifying the cost if you have a lot of PCs in your household.”

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.

What is iolo's Whole Home License?

The Whole Home License® is iolo’s licensing policy that allows you to install and keep your software running on all of your compatible devices within the same home. Previously, users were allowed to install and license their iolo software simultaneously on a maximum of three PCs. Under the Whole Home License, a single activation key allows you to use your iolo software on all of your PCs, other than any PCs you use for business purposes. What you need to know about Whole Home Licensing

  • You, your spouse, and your relatives living within the same household may use the same license on any number of PCs that you own which are not used for business.
  • For full legal terms and conditions, see https://www.iolo.com/company/legal/eula/

To install your iolo product on additional PCs:

  1. On the additional computer, download the latest version of your iolo product. Choose from the list of downloads offered here.
  2. Follow the steps in the installation wizard, and enter the same Activation Key that you used to install on your original computer.

You can view the Activation Key on the original computer from within System Mechanic > red menu bar > key icon > Activation Key.
