STOPzilla Optimizer is a software designed by iS3 to repair your system's registry. Like other registry scanners, STOPzilla Optimizer has a welcome wizard that takes an automatic system backup of your system's registry before starting an initial scan of your PC. The interface of the software is intuitive, with tools and tab labels helping you to find the tool you're looking for within the software. The registry scan took 50 seconds and the software found 164 issues with the registry. The results screen, though, didn't provide detailed information about the issues found during the scan or advice about how to fix registry errors. A single repair button automatically resolves the issues based on the software's recommendations.

The software includes a Registry Optimizer tool that defragments your registry like many other registry cleaner software. After running the software's different tools, it did increase the performance of our test computer, but only by .17 percent, the lowest of any registry repair software we tested.

The safety features included with STOPzilla Optimizer are good for helping you protect your system's information. The backup tool runs automatically when you first use the software, which helps you to avoid any damage that can occur when you repair your registry. The backup tool includes the option of a full or partial backup, letting you conserve room on your hard drive. The exclusion list lets you protect sensitive areas of your computer from scanning and avoid potential registry repair errors. The software does have an undo feature, which lets you undo individual registry repairs done by the software. This saves you time from having to do a complete registry restoration should you make a mistake by accidentally deleting a single sensitive file.

STOPzilla Optimizer only comes with a single software license, which is standard for most software in this field. STOPzilla does offer additional software licenses to multiple computers, up to five, for an additional fee. The help and support offered by iS3 includes 24/7 telephone support in both the USA and Canada. The STOPzilla Optimizer website includes live chat that is good for both questions you might have before the purchase of the software and technical support questions you may have after using the software. STOPzilla Optimizer has links in the software that will take you to the FAQs section of iS3 website and connect you to a form email webpage for email support.


The help, support and safety features included on STOPzilla Optimizer are quite good. The automatic backup of the registry ensures that your system's information will remain safe during registry cleaning. Yet, the registry scan tool and defragmentation tool did little to increase the performance of our test machines.


STOPzilla Optimizer offers good safety features like an undo feature, full and partial registry backup and an exclusion list.


The scan results screen doesn't provide detailed information about found registry errors.


There are many good help, support and safety features included with STOPzilla Optimizer, but the performance of the software was lacking.
